Kurzbeschreibung (Abstract)

Double-perovskite series of Ba2Co1-x Fe (x) ReO6 (x = 0, 0.2, 0.4, and 0.5) were prepared as single-phase materials using the conventional solid-state reaction method and studied by X-ray powder diffraction and magnetization techniques. The Rietveld analysis of the X-ray diffraction patterns showed a partial disordering in the Re and Fe/Co layers on the B sites of the double perovskites, which played a central role in the structural and magnetic properties of the compounds. The findings showed that symmetry was cubic (Fm3m) for all of the samples. The magnetization versus temperature measurements at H = 500 Oe revealed that the Ba2CoReO6 and Ba2Co0.8Fe0.2ReO6 samples showed antiferromagnetic state and exhibited a paramagnetic-ferromagnetic transition for x = 0.4 and 0.5. The Curie temperature was also noted to increase with the increase in the Fe content.
