Abstract
The temperature dependences of magnetic entropy change and refrigerant capacity have been calculated for a maximum field change of ΔH = 30 kOe in as-quenched ribbons of the ferromagnetic shape memory alloy Ni50.4Mn34.9In14.7 around the structural reverse martensitic transformation and magnetic transition of austenite. The ribbons crystallize into a single-phase austenite with the L21-type crystal structure and Curie point of 284 K. At 262 K austenite starts its transformation into a 10-layered structurally modulated monoclinic martensite. The first-and second-order character of the structural and magnetic transitions was confirmed by the Arrott plot method. Despite the superior absolute value of the maximum magnetic entropy change obtained in the temperature interval where the reverse martensitic transformation occurs (|ΔSmaxM| = 7.2 J kg-1 K-1) with respect to that obtained around the ferromagnetic transition of austenite (|ΔSmaxM| = 2.6 J kg-1 K-1), the large average hysteretic losses due to the effect of the magnetic field on the phase transformation as well as the narrow thermal dependence of the magnetic entropy change make the temperature interval around the ferromagnetic transition of austenite of a higher effective refrigerant capacity (RCmagneff = 95 J kg-1 versus RCstructeff = 60 J kg-1).
