Magnetocaloric effect in In doped YbMnO3

Magnetic and magnetocaloric (MCE) properties of Yb0.9In0.1MnO3 and Yb0.8In0.2MnO3 polycrystalline samples are presented in this paper. Isothermal magnetization measurements reveal a field induced magnetic transition. Magnetic entropy change of 2.34±0.35 J/mole-K for Yb0.9In0.1MnO3 and 2.64±0.38 J/mole-K for Yb0.8In0.2MnO3 field change ΔH =10 KOe is observed around the ferromagnetic ordering temperature of Yb3+. Values of relative cooling power for the same field change are found to be 38.03±9 J /mol, and 40.90±10 J/mol for Yb0.9In0.1MnO3 and Yb0.8In0.2MnO3, respectively. These values suggest In doped YbMnO3 may be a potential candidate for magnetic refrigerant at low temperatures.
