摘要: We have confirmed the significant anisotropy of generalised magnetic susceptibility in paramagnetic and antiferromagnetic phase fcc Mn–Ni alloys. In this paper detailed account experiments performed on Mn0.71Ni0.29 alloy is given. Our main result for that correlation length larger direction parallel to axis than perpendicular one by a factor 1.6. The spin-wave velocity observed at 15 K higher 1.2. These results are similar Mn0.62Ni0.38 alloy. indicate carriers more localized interactions less extended alloys with Ni concentration.
