Magnetic Properties of Spinel FeCr\(_{2}\)S\(_{4}\) in High Magnetic Field

We studied temperature and magnetic field dependence of magnetization, \(M(T)\) and \(M(B)\), on thiospinel FeCr\(_{2}\)S\(_{4}\). We observed a step-like anomaly at \(T_{OO} \sim\) 9 K for \(M\)(\(T\)) attributed to an orbital order transition in magnetic field 0 \(< B \leq\) 7 T. Furthermore, a...

Description
Summary:We studied temperature and magnetic field dependence of magnetization, \(M(T)\) and \(M(B)\), on thiospinel FeCr\(_{2}\)S\(_{4}\). We observed a step-like anomaly at \(T_{OO} \sim\) 9 K for \(M\)(\(T\)) attributed to an orbital order transition in magnetic field 0 \(< B \leq\) 7 T. Furthermore, also for \(M\)(\(B\)), an step-like anomaly appears at \(B_{c} \sim\) 5.5 T 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 FeCr\(_{2}\)S\(_{4}\) in \(T\
