EnglishThe magnetic-moment density distribution in two alloys near the stoichiometric MnPt3 alloy composition has been measured by means of the polarized-neutron technique. It has been found that in the perfectly ordered lattice Mn and Pt atoms are ferromagnetically aligned, while in the presence of disorder the Mn atoms which happen to occupy the Pt sites give a negative contribution to the magnetization. The spherically averaged distribution for Mn atoms is independent of whether the atom is on a Mn or Pt site. However, Mn atoms on Mn sites are spherically symmetric, while Mn atoms on Pt sites have aspherical distributions.
