Abstract
Abstract In this paper, we have investigated the magnetocaloric effect (MCE) and its modulation by electric field in La0.325Pr0.3Ca0.375MnO3 (LPCMO) films grown on (0 1 1)-oriented PMN-PT substrates. As a typical perovskite manganite with phase separation, the LPCMO bulk shows a considerable MCE, but the MCE of the LPCMO films has never been investigated. We found that the LPCMO films exhibit a MCE over a wide temperature range. A modulation of magnetization by electric field has been observed in the temperature dependent (M−T) and magnetic field dependent (M−H) curves. As a result, enhanced magnetic entropy change and refrigeration capacity by about 4% under an electric field of +6 kV/cm has been demonstrated.
