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