The electron spin-density space distribution in ferromagnetic Heusler alloys

The hyperfine magnetic fields on Mn⁵⁵, Co⁵⁹, Al²⁷ and Si²⁹ were measured by the spinecho technique in several systems of Heusler alloys. The concentration dependence of local magnetic moments of Mn and Co ions in different lattice positions was determined and the space distribution of delocalized electron spin-density was analyzed. The hyperfine fields on spelements were calculated using the main theoretical models.
