Abstract

It has been known that A₂B\´B"O₆ typed compounds (A is an alkaline-earth or rare-earth element, B\´ and B" are different transition-metal elements) belong to the double perovskite family, which have attacted considerable interes due to their complex electrical-magnetic properties. Among these, La₂NiMnO₆ is a ferromagnetic (FM) semiconductor, and considered as one of the most promising materials for applications in spintronic devices. Though the crystal structure, electromagnetic, and magnetic properties of this material have been widely studied, the nature of FM interactions and magnetocaloric effect (MCE) has not been fully understood yet. Within this context, it is essential to investigate the correlation between the MCE and critical behavior near the FM-para-magnetic (PM) transition in this material.
