Magnetic properties of the reentrant CdGa2−2Cr2Se4

Abstract We report the first results of the electron paramagnetic resonance (EPR) and temperature dependence of ZFC and FC magnetization data in the CdGa 2−2 x Cr 2 x Se 4 compounds. The linewidth and the resonance field behavior of the EPR spectra were obtained as a function of temperature for sample with x =0.2. The X-ray diffraction data shows that the samples crystallize in the tetragonal system and the low field magnetization data for x =0.2 clearly presents a ferrimagnetic transition at T c =125 K. The Curie temperature, magnetic effective moment and others parameters were obtained.
