Abstract

In this paper, we trace the structure and magnetic properties of Ni-Al and Ni-Mn-Al compound produced by Arc melting. Tracing have been done by comparing the structure and magnetic properties of Ni3Al, Ni2MnAl and Ni50Mn32Al18 alloys system. Analysis structure on Ni2MnAl show that the atomic position of Mn and Al are at different site. But for Ni50Mn32Al18, the atomic position of Mn and Al occupy the same site. Ni3Al and Ni2MnAl do not show ferromagnetic phenomena, but Ni50Mn32Al18 alloys system have shown ferromagnetic phenomena. It could be expected that one of the Ni-Mn-Al system (Ni50Mn32Al18 ) could a parental compound for magnetocaloric materials by partial substitute of Al by Mn in its lattice.
