Abstract

The entropy change ΔS between the high-temperature cubic phase and the low-temperature tetragonally based martensitic phase of Ni2+xMn1−xGa (x=0–0.20) alloys was studied. The experimental results obtained indicate that ΔS in the Ni2+xMn1−xGa alloys increases with the Ni excess x. The increase of ΔS is presumably accounted for by an increase of magnetic contribution to the entropy change. It is suggested that the change in modulation of the martensitic phase of Ni2+xMn1−xGa results in discontinuity of the composition dependence of ΔS.
