Theoretical study of diluted Co/Cu alloys

Abstract This study employs the self-consistent Green's function method to study the magnetic properties of diluted Co x Cu 1 - x alloys from a consideration of their spin dynamics characteristics. The numerical results show that in dilute cobalt concentrations (i.e. x ⩽ 0.4 ), the critical temperatures vary linearly with x for different itinerant carrier concentration conditions. Interestingly, the carrier concentration does not affect the degree of dependency of the temperature on the cobalt concentration when the carrier concentration is less than the atomic number concentration of the alloy.
