Electronic structure of transition metal-metalloid crystalline and glassy alloys

The results of magnetic and Moessbauer measurements on 3d transition metal-light metalloid intermetallic compounds and metallic glasses are discussed on the basis of the donor model. This model can predict the maximum possible value of the magnetic moment up to 50 at% metalloid concentration. The localization of the electronic states with the increasing metalloid content is also shown. (author)
