Description

The nonvolatile electric field control of the magnetocaloric effect (MCE) can be achieved in the Ni-Co-Mn-Sn/(011)0.7Pb(Mg1/3Nb2/3)O3–0.3PbTiO3 composite with the application of asymmetric bipolar electric fields. By controlling the electric fields, different nonvolatile strain states can be obtained and transmit to Ni-Co-Mn-Sn ribbon, which leads to an increase of phase transition temperature. As a result, the effective magnetic refrigeration temperature region can be extended by applying the asymmetric bipolar electric fields. This nonvolatile control of the MCE would have promising applications in designing more efficient magnetocaloric devices.
