Magnetic properties of the reentrant CdGa<inf>2-2x</inf>Cr <inf>2x</inf>Se<inf>4</inf>

Abstract:

We report the first results of the electron paramagnetic resonance (EPR) and temperature dependence of ZFC and FC magnetization data in the CdGa 2-2xCr2x 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. © 2003 Elsevier B.V. All rights reserved.
