dc.description.abstract	We have studied the effect of magnetic field on a nonstoichiometric Heusler alloy Ni(50)Mn(35)In(15) that undergoes a martensitic as well as a magnetic transition near room temperature. Temperature dependent magnetization measurements demonstrate the influence of magnetic field on the structural phase transition temperature. From the study of magnetization as a function of applied field, we show the occurrence of inverse-magnetocaloric effect associated with this magneto-structural transition. The magnetic entropy change attains a value as high as 25 J/kg K (at 5T field) at room temperature as the alloy transforms from the austenitic to martensitic phase with a concomitant magnetic ordering.	en_US
