Robust $d$-wave altermagnetism in $\mathrm{XCr_2Y_2O}$ (X=K, Rb, Cs; Y=S, Se, Te) family

San-Dong Guo

RbCr2Se2O is a robust d-wave altermagnetic metal because its C-type and G-type magnetic states differ strongly in energy.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

we predict that the experimentally synthesized RbCr2Se2O is a robust d-wave altermagnetic metal, since the energy difference between C-type and G-type configurations is large, which is independent of electron correlation strength and van der Waals interaction.

C2weakest assumption

DFT calculations with standard functionals and varying U accurately capture the true ground-state energy ordering and its independence from correlation strength in the real synthesized material.

C3one line summary

RbCr2Se2O is predicted as a robust d-wave altermagnetic metal where in-plane uniaxial strain generates net magnetic moment via piezomagnetic effect, distinguishing G-type AFM.
