In this work,we tuned the magnetostructural transformation and the coupled magnetocaloric properties of Mn48-xVxNi42Sn10 (x =0,1,2,and 3) ferromagnetic shape memory alloys prepared by means of partial replacement of Mn by V.It is observed that the martensitic transformation temperatures decrease with the increase of V content.The shift of the transition temperatures to lower temperatures driven by the applied field,the metamagnetic behavior,and the thermal hysteresis indicates the first-order nature for the magnetostructural transformation.The entropy changes with a magnetic field variation of 0-5 T are 15.2,18.8,and 24.3 J.kg-1.K-1 for the x =0,1,and 2 samples,respectively.The tunable martensitic transformation temperature,enhanced field driving capacity,and large entropy change suggest that Mn48-xVxNi42Sn10 alloys have a potential for applications in magnetic cooling refrigeration.
