La 2 NiMnO 6 is a unique compound of multiferroics that exhibits two magnetic transitions of Curie points T C1 and T C2 below room temperature on a partial conversion of charge carriers, Ni 2+ → Ni 3+ and Mn 4+ → Mn 3+ , stabilized with O 2- vacancies in distorted octagons in a double perovskite of a spin cluster (glass), wherein the spins freezing at a critical T g point at lower temperatures. The peak temperature and irreversibility temperature shifted to the lower temperature. The dc magnetization M (T) measurements indicate random ferromagnetic and antiferromagnetic interactions and multiple magnetic transitions. The critical slowing properties signify the spin-glass nature proved by the thermomagnetic relaxation measure.
