Multicaloric effect in multiferroic Y₂CoMnO₆

We have investigated multiple caloric effects in multiferroic Y₂CoMnO₆. 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 (−ΔS_M^max) 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 (−ΔS_E^max) 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.
