Abstract
The variations of the martensitic transformation starting temperature TMS and the Curie temperature TC in Ni-Fe-Ga alloys have been investigated by substituting with several kinds of the fourth elements. By partial substitution of Co or Cu for Ni, TC increases and TMS decreases. In particular, the increase of TC is remarkable in the Ni54−xCoxFe19Ga27 alloy, which is related to the strong Ni-Co and Co-Fe exchange interactions. For the Ni54Fe19−xMnxGa27 alloys, TC slightly increases with the increase of Mn content, in analogy with the Ni52FexMn21−xGa27 alloys. From the present study, it is demonstrated that both TC and TMS of the Ni-Fe-Ga alloys can be effectively controlled by selecting the substituents.
