Magnetic properties of the reentrant CdGa2-2xCr2xSe4

We report the first results of the electron paramagnetic resonance (EPR) and temperature dependence of ZFC and FC magnetization data in the CdGa2-2xCr2x Se4 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 Tc=125 K. The Curie temperature, magnetic effective moment and others parameters were obtained
