Abstract
A considerable magnetic entropy change has been observed in Ni51.5Mn22.7Ga2
5.8 alloys under a field of 0.9 T. This change originates from a sharp magn
etization jump which is associated with a martensitic to austenitic structu
re transition. The large low field entropy change and the adjustable marten
sic-austensic transition temperature indicate a great potential of Ni-Mn-Ga
as working materials for magnetic refrigerants in a wide temperature range
