Magnetocaloric effect in Ni2MnIn alloy
Magnetocaloric effect investigations of polycrystalline Ni <sub>50,2</sub>Mn <sub>39,8</sub>In <sub>10</sub> alloy are presented. Alloy was prepared by arc melting in the argon atmosphere. Influence of magnetic field on the temperature of the martensitic transformation is established according to the results of electrical resistance studies in the temperature interval of in phase transition. It is shown that in a magnetic field with strength of 1.55 MA/m martensitic transformation temperature is decreased by 4.8 K. The direct magnetocaloric effect in the temperature interval of magnetic transition and the inverse one in the structural phase transition temperature range are observed.
