Multicaloric effect in multiferroic Y₂CoMnO₆

Abstract

We have investigated multiple caloric effects in multiferroic Y2CoMnO6.\nPolycrystalline sample prepared by solid state method has shown a ferromagnetic\nCurie temperature 75 K with second order phase transition; a maximum magneto\nentropy change -$\\Delta$S_{Mmax}) of ~ 7.3 J/kg K with reasonable relative\ncooling power 220 J/kg is found without thermal and magnetic hysteresis loss.\nElectric field driven entropy change (-$\\Delta$S_{Emax}) of ~ 0.26 J/m^3 K\nobtained using the Maxwells relation and estimated magnetically induced total\ntemperature change of 5.45 K around Curie temperature that confirms the\nmulticaloric effect in the sample.\n
