ChemInform Abstract: Electrical Resistivity and Ferromagnetism in Ni‐Ga Alloys

Abstract

ChemInform Abstract containing up to 26 at.% Ga is studied as a function of Ga content. The decrease of the magnetic resistivity with increasing Ga content is smaller than expected from calculations on the basis of the localized spin model, suggesting the presence of an additional contribution to the magnetic resistivity. This excess magnetic resistivity may be due to the interband s-d transition caused by an increase in the number of hole carriers with increasing Ga concentrations.
