Magnetic phase transition of CrCl3-GIC

Magnetic ordering of stage-3 CrCl 3 -GIC is investigated by thermoremanent magnetization M r , ac susceptibility x ′ and nonlinear magnetization M ′ 3ω measurements. M r indicates a single phase transition at T c of a spin glass type, but x ′ and M ′ 3ω reveal two anomalies, suggesting a possibility of another transition below T c .
