  • ABSTRACT: We studied the composition dependence of the critical temperatures and of the magnetocaloric properties of Co doped NiMnGa alloys around the Mn-rich composition Ni50Mn30Ga20. By varying the Co and Mn content we have been able to tune the critical temperatures and to obtain a complete reverse martensitic transformation between paramagnetic martensite and ferromagnetic austenite. Unlike the Co-free alloys, high values of inverse magnetocaloric effect are associated to such a reverse transformation. The possibility to change the sign of the magnetocaloric effect by stoichiometric control of NiCoMnGa makes these materials interesting for magnetic refrigeration applications. (literal)
