Direct and Inverse Magnetocaloric Effect in Ni_1.81Mn_1.64In_0.55 Multifunctional Heusler Alloy

Abstract:

The magnetocaloric effect (MCE) in Ni_1.81Mn_1.64In_0.55 Heusler alloy has been measured by the direct method. The field dependences of the magnetization were obtained. The phase transition temperatures were determined. The maximal adiabatic temperature change ΔT_ad near the Curie temperature is 1.8 K under the magnetic field change ∆H = 18 kOe. The inverse MCE (∆T_ad= -3.72 K) in the same field change takes place near the temperature of martensitic transformation.
