Extended X-ray Absorption Fine Structure (EXAFS) studies on Ni 50 Mn 25+ x In 25− x have been carried out at the 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 gives 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 3 d -Mn 3 d hybridization in the magnetism of the martensitic phase of these alloys.
