Magnetic entropy change and critical exponents in double perovskite Y2NiMnO6

Abstract

We report on the magnetic entropy change and the critical exponents in the double perovskite manganite Y2NiMnO6 with a ferromagnetic to paramagnetic transition TC=85K. For a magnetic field change of 80kOe, a maximum magnetic entropy change -6.57 J /kg K is recorded around TC. The corresponding relative cooling power (134 J / kg) is appreciable towards potential application as a magnetic refrigerant. The critical exponents, beta and gamma satisfy well to values derived for a 3D Heisenberg ferromagnet.
