Abstract

We studied temperature and magnetic field dependence of magnetization, M(T) and M(B), on thiospinel FeCr₂S₄. We observed a step-like anomaly at T_OO∼9K for M(T) attributed to an orbital order transition in magnetic field 0 <B≤7T. Furthermore, also for M(B), the step-like anomaly appears at B_c∼5.5T below T_OO. This suggests an existence of a magnetic phase boundary at B_c in T<T_OO. Because the anomaly at B_c of M(B) exists in the orbital ordered phase, the spin structure of FeCr₂S₄ in T<_TOO is strongly coupled with the lattice of the system.
