Abstract
Diluted by indium, the chalcogenide spinel CdCr 2−2 x In 2 x Se 4 is in an SG state. The temperature dependence of the magnetization ( M) with comparison to the ordered magnetic state is modified by non-zero density of states in the energy band gap. Also, the unidirectional magnetic anisotropy is attributed to the SG state due to the Dzyaloshinskii–Moriya (DM) interaction. The investigated samples of CdCr 2−2 x In 2 x Se 4 were obtained by an RF sputtering technique. We present the temperature (from 5 to 160 K) dependence of M, unidirectional magnetic anisotropy field H an and surface magnetic anisotropy constant K s t . The magnetic parameters were determined from the temperature dependence of the ferromagnetic resonance (FMR) and spin wave resonance (SWR) data.
