Abstract

We report an experimental demonstration of the magnetoelectrocaloric effect (MECE) in multiferroic $\mathrm{GdFeO_3}$ . The temperature of the magnetic material changes when an external electric field is suddenly changed. MECE is the largest below the ordering temperature of Gd moments and modifiable by a magnetic field, suggesting that the ferroelectric transition affects MECE. The observed MECE shows a higher energy efficiency than typical magnetocaloric effects and adiabatic nuclear demagnetization. The present findings provide a proof of concept of MECE in multiferroics.
