The experimentally measured spin density of a partially ordered Ni78Mn22 alloy is used to study the magnetic state of Mn within an fcc environment. The present data, together with those obtained by Petrillo, Sacchetti, and Scafi [Phys. Rev. 44, 9418 (1991)), are used to determine the form factor and magnetic moment of the Mn atoms in various atomic configurations. It is found that Mn carries a magnetic moment with fluctuating spin, while an appreciable charge transfer from Mn to Ni is suggested.

Abstract
The experimentally measured spin density of a partially ordered Ni78Mn22 alloy is used to study the magnetic state of Mn within an fcc environment. The present data, together with those obtained by Petrillo, Sacchetti, and Scafi [Phys. Rev. 44, 9418 (1991)), are used to determine the form factor and magnetic moment of the Mn atoms in various atomic configurations. It is found that Mn carries a magnetic moment with fluctuating spin, while an appreciable charge transfer from Mn to Ni is suggested.File in questo prodotto:
