The pith

1T-CrTe2/FeTe heterostructures induce superconductivity at 12 K with Meissner effect and nonreciprocal transport.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper grows a two-dimensional ferromagnet, 1T-CrTe2, on an antiferromagnetic FeTe layer and reports that the resulting stacks become superconducting below about 12 K. Magnetic force microscopy detects the Meissner effect on the 1T-CrTe2 surface, while transport measurements show strong nonreciprocal current flow quantified by a large magneto-chiral anisotropy coefficient. The authors present the interface as a platform where magnetism and superconductivity coexist without requiring topological insulators, opening routes to magnetically tunable superconducting diodes.

Core claim

Stacking non-topological 1T-CrTe2 on FeTe produces interface superconductivity at Tc approximately 12 K. Magnetic force microscopy images confirm the Meissner effect on the 1T-CrTe2 surface. Electrical transport reveals pronounced nonreciprocal charge transport with a large magneto-chiral anisotropy coefficient, consistent with a magnetically controllable superconducting diode effect.

What carries the argument

The 1T-CrTe2/FeTe interface, which induces superconductivity and breaks reciprocity through the adjacent ferromagnetism.

If this is right

Superconductivity emerges at the boundary between a room-temperature ferromagnet and FeTe without topological protection.
Nonreciprocal transport appears together with the superconducting state, quantified by a large magneto-chiral anisotropy coefficient.
The heterostructure supplies a concrete platform for testing magnetically switched superconducting diode behavior.
The same stacking approach may be extended to other two-dimensional ferromagnets on FeTe.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

Similar interface superconductivity might appear when other high-Curie-temperature 2D magnets replace 1T-CrTe2.
The observed nonreciprocity could be tuned by rotating the magnetization direction in the 1T-CrTe2 layer.
If the effect survives in micron-scale devices, it would allow direct electrical readout of the superconducting diode polarity.

Load-bearing premise

The superconductivity and Meissner effect come from the interface itself rather than from defects, strain, or properties already present in either separate layer.

What would settle it

Transport and microscopy measurements on bare 1T-CrTe2 films or bare FeTe films that show no superconductivity or no Meissner effect would indicate the interface is not required.

read the original abstract

Interface-induced superconductivity has recently been achieved by stacking a magnetic topological insulator layer on an antiferromagnetic FeTe layer. However, the mechanism driving this emergent superconductivity remains unclear. Here, we employ molecular beam epitaxy to grow a 1T-CrTe2 layer, a two-dimensional ferromagnet with a Curie temperature up to room temperature, on a FeTe layer. These 1T-CrTe2/FeTe heterostructures show superconductivity with a critical temperature of ~12 K. Through magnetic force microscopy measurements, we observe the Meissner effect on the surface of the 1T-CrTe2 layer. Our electrical transport measurements reveal that the 1T-CrTe2/FeTe heterostructures exhibit nonreciprocal charge transport behavior, characterized by a large magneto-chiral anisotropy coefficient. The enhanced nonreciprocal charge transport in 1T-CrTe2/FeTe heterostructures provides a promising platform for exploring the magnetically controllable superconducting diode effect.

Desk Editor's Note private letter to a colleague

1T-CrTe2/FeTe stacks show Tc~12 K superconductivity with Meissner imaging and nonreciprocal transport, but single-layer controls are missing to confirm the interface is the source.

read the letter

The main point is a new heterostructure: MBE-grown 1T-CrTe2 on FeTe that becomes superconducting near 12 K, with MFM showing Meissner expulsion on the CrTe2 surface and transport data giving a large magneto-chiral anisotropy coefficient. This is distinct from the magnetic TI/FeTe stacks in the cited literature because CrTe2 is a non-topological ferromagnet with high Curie temperature. The paper does a straightforward job of reporting the growth, the imaging, and the transport numbers on this specific pair. The central claim that the superconductivity and nonreciprocity come from the interface rather than strain, defects, or one of the layers alone rests on the assumption that bare FeTe and bare CrTe2 do not show the same behavior. The abstract and stress-test note give no sign of those single-layer controls, which leaves the origin open. If the full manuscript has resistivity curves and MFM on the individual films grown under identical conditions, that would close the gap; otherwise it is the main soft spot. This is for groups working on interface magnetism and superconducting diodes. A reader who wants concrete data on a fresh material system will get something usable from the measurements. It is worth sending to referees because the material combination and the direct imaging are new enough to merit checking, even if the controls need to be added.

Referee Report

2 major / 2 minor

Summary. The paper reports MBE growth of 1T-CrTe2/FeTe heterostructures that exhibit superconductivity with Tc ≈ 12 K. MFM measurements show the Meissner effect on the 1T-CrTe2 surface, while transport measurements reveal nonreciprocal charge transport characterized by a large magneto-chiral anisotropy coefficient, positioning the system as a platform for magnetically controllable superconducting diode effects.

Significance. If the interface origin of the superconductivity is established, the work extends interface-induced superconductivity to a ferromagnetic 2D material on FeTe, adding a new materials platform with room-temperature ferromagnetism in one layer. The combination of Meissner-effect confirmation and quantified nonreciprocal transport would be of interest for superconducting electronics.

major comments (2)

[Abstract / Results] The central claim is that superconductivity (Tc ~12 K) and the Meissner effect arise at the 1T-CrTe2/FeTe interface. However, the manuscript provides no resistivity or MFM data on bare FeTe or bare 1T-CrTe2 films grown under identical MBE conditions. Without these controls, strain, defects, or intrinsic properties of either layer cannot be excluded as the source of the observed transition (see Abstract and Results sections).
[Abstract] The abstract states clear experimental observations but supplies no raw data, error bars, or exclusion criteria for the Tc determination or the MCA coefficient extraction. This limits verification of the reported values and the claim of 'large' nonreciprocity.

minor comments (2)

[Transport measurements] Clarify the exact definition and units of the magneto-chiral anisotropy coefficient and the fitting procedure used to extract it from the transport data.
[Introduction] The introduction references prior magnetic-TI/FeTe work but does not explicitly compare growth conditions or Tc values with the present CrTe2/FeTe system.

We thank the referee for the constructive comments, which help clarify the presentation of our results on interface-induced superconductivity in 1T-CrTe2/FeTe heterostructures. We address each major comment below.

Referee: [Abstract / Results] The central claim is that superconductivity (Tc ~12 K) and the Meissner effect arise at the 1T-CrTe2/FeTe interface. However, the manuscript provides no resistivity or MFM data on bare FeTe or bare 1T-CrTe2 films grown under identical MBE conditions. Without these controls, strain, defects, or intrinsic properties of either layer cannot be excluded as the source of the observed transition (see Abstract and Results sections).

Authors: The referee is correct that the presented manuscript lacks explicit control data on bare FeTe and bare 1T-CrTe2 films. Such measurements are necessary to strengthen the interface-origin claim. In the revised manuscript we will add resistivity versus temperature curves for bare layers grown under identical MBE conditions. We will also include MFM images on bare films to confirm the absence of the Meissner effect, noting that bare 1T-CrTe2 is ferromagnetic without superconductivity and bare FeTe is antiferromagnetic. These additions will be placed in the Results section with appropriate discussion. revision: yes
Referee: [Abstract] The abstract states clear experimental observations but supplies no raw data, error bars, or exclusion criteria for the Tc determination or the MCA coefficient extraction. This limits verification of the reported values and the claim of 'large' nonreciprocity.

Authors: We agree that the abstract is concise and omits quantitative details on uncertainties and analysis criteria. The main text and figures report Tc with error bars (defined via the temperature at which resistance falls below the noise floor) and the MCA coefficient with fitting uncertainties. To address the concern we will revise the abstract to include approximate values with uncertainties (e.g., Tc ≈ 12 ± 1 K) and state that detailed extraction procedures and raw data appear in the Results section. The claim of 'large' nonreciprocity will be supported by explicit comparison to prior literature values in the revised text. revision: partial

full rationale

This is a purely experimental paper reporting MBE growth of 1T-CrTe2/FeTe heterostructures followed by direct measurements of Tc~12 K superconductivity, MFM-observed Meissner effect, and transport-based nonreciprocal charge transport. No equations, derivations, fitted parameters, or first-principles predictions appear in the provided text or abstract; all claims are observational outputs rather than reductions of any internal inputs. The derivation chain is therefore self-contained with no self-definitional, fitted-prediction, or self-citation load-bearing steps.
