Multicaloric effect in multiferroic Y₂CoMnO₆

We have investigated multiple caloric effects in multiferroic Y 2 CoMnO 6 . The polycrystalline sample prepared by the solid state method has shown a ferromagnetic Curie temperature ~75 K with a second order phase transition; a maximum magneto entropy change of ~ 7.3 J kg −1 K −1 with a reasonable relative cooling power ~220 J kg −1 is found without thermal and magnetic hysteresis loss. An electric field driven entropy change of ~ 0.26 J m −3 K −1 was obtained using the Maxwell's relation and estimated magnetically induced a total temperature change of ~5.45 K around the Curie temperature that confirms the multicaloric effect in the sample.
