Role of Ni-Mn hybridization in magnetism of martensitic state of Ni-Mn-In shape memory alloys

Abstract

Extended X-ray Absorption Fine Structure (EXAFS) studies on Ni${}_{50}$Mn${}_{25+x}$In${}_{25-x}$ have been carried out at Ni and Mn K edge as a function of temperature. Thermal evolution of nearest neighbor Ni-Mn and Mn-Mn bond distances in the martensitic phase give a clear evidence of a close relation between structural and magnetic degrees of freedom in these alloys. In particular, the study highlights the role of Ni 3d - Mn 3d hybridization in the magnetism of martensitic phase of these alloys.
