摘要: In the first part an approximate method to treat problem of one impurity atom in otherwise pure metal is developed on basis tight‐binding approximation. The capable taking into account degeneracy 3d bands and mixing with 4s band. It shown that can each atomic orbital separately.In second part, dilute Ni alloys other transition metals are discussed a simple model. calculation substantiates Friedel's theory these alloys. negative magnetic moments Cr V Fe also discussed.
