Electronic structure and magnetic properties of RNi5−xCux alloys (R=Y, La, Ce)

Abstract

A study is made of the electronic structure and magnetic properties of RN5−xCux alloys (R=Y, La, Ce). The influence of substitution of nickel by copper on the features of the band structure and behavior of the magnetic susceptibility of these alloys is investigated. An analysis is made of the electronic states and interactions responsible for the magnetic properties of RNi5−xCux alloys.
