Ferromagnetic Interactions in Chromium (III) Doped YMnO_3

摘要

Both of the reported compounds with compositions YMn_(1-x)Cr_xO_3 (x=0.1 and 0.2) are synthesized by using the conventional solid state reaction method and their magnetic properties are analyzed vigilantly. The XRD pattern reveals the hexagonal structure of the reported compounds with space group P6_3cm (25-1079). The in-depth analysis of the magnetic measurements reveals the enhancement in the ferromagnetic character with Cr doping in YMnO_3 compounds. The observed enhancement in the ferromagnetism is found to be due to the increased double exchange interactions among the Cr~(3+)and Mn~(3+) ions with Cr doping.
