Abstract

Abstract The substantial change in a magnetic Curie temperature of 294 K and degree of magnetic order were investigated in a 10-nm La0.7Sr0.3MnO3/Pb(Mg1/3Nb2/3)O3-PbTiO3(001) two-phase composite material through pure voltage control in the absence of external magnetic fields. The mass-specific isothermal entropy change calculated was greater than 2 J/(kg × K), obtained using an electric field of 7 kV/cm, which serves as proof of the concept of using the magnetocaloric effect in zero-applied magnetic fields for sizeable entropy change. Fabrication strategies of the two-phase multiferroics ensembles are also discussed.
