AbstractWe propose a conception - coupled caloric effect where the enhanced caloric effects originate from the coupling among magnetic, ferroelectric, and structural degrees of freedom. Specifically, as the magneto-electric case, the magnitude of the coupled caloric effect was evaluated for a ferromagnetic-ferroelectric system using a phenomenological calculation based on Landau phase transition theory. The isothermal entropy change is greatly enhanced by increasing the magneto-electric coupling strength. This work indicates that the caloric effect in a ferromagnetic-ferroelectric coupled system consists of pure magnetic entropy change (Delta S-M), pure ferroelectric one (Delta S-E), and coupled one (Delta S-ME) that plays a significant part. The counterpart of the last one in magneto-structural coupled system was usually neglected. Our study provides a route to energy-efficient refrigeration via realization of coupling among various ferroic orders. (C) 2013 Elsevier B.V. All rights reserved.
