In Fe_x NbSe2, increasing iron content drives transitions from paramagnetism to spin-glass to long-range antiferromagnetism (max TN=175 K at x=0.25 with ordered 2a0 x 2a0 Fe superlattice) then reentrant spin-glass, with transport anomalies confirming the magnetic evolution.

Stoichiometry-Controlled Structural Order and Tunable Antiferromagnetism in $\mathrm{Fe}_{x}\mathrm{NbSe_2}$ ($0.05 \le x \le 0.38$)
In Fe_x NbSe2, increasing iron content drives transitions from paramagnetism to spin-glass to long-range antiferromagnetism (max TN=175 K at x=0.25 with ordered 2a0 x 2a0 Fe superlattice) then reentrant spin-glass, with transport anomalies confirming the magnetic evolution.
