Abstract

Annealing plays an important role to adjust structures and properties of ferromagnetic shape memory alloys. Thermal annealing effects on structural and magnetic properties of Fe46Mn26Ga28 FSMA have been investigated at different temperatures. Rietveld refinements of neutron diffraction patterns display that the formation of the phase in Fe46Mn26Ga28 annealed at 1073 K is Fe-rich Ga-poor cubic phase. The atomic occupancies of the alloys are determined due to the neutron's capability of differentiating transition metals. Different annealing treatment introduces magnetic characteristic that is associated with distinctive structural changes in crystal.
