Effect of Co substitution on magnetic and magnetocaloric properties in multiferroic hexagonal YMnO3



Polycrystalline YMn1−x Co x O3 with x ranging from 0 to 0.1 was synthesized by solid-state reaction method. The magnetic and magnetocaloric properties were investigated by superconducting quantum interference design magnetometer. With the increasing of Co-doping, the YMn1−x Co x O3 shows complex magnetic properties, including the existence of ferromagnetic component and spin glass state. The Curie temperature and maximum magnetic entropy change are also strongly dependent on Co content. Those results were ascribed to the complex mixed valence characteristics of Mn ions originated from the Co-doping.
