Magnetic Susceptibilities of Transition Metal Solutes in Liquid Se–Te Alloys

抄録

The magnetic susceptibilities of 3d-transition metal solutes in liquid Se–Te alloys have been measured in order to study the s-d interaction between the localized d-states and the conduction electrons. The additional susceptibilities of transition metal solutes except V increase monotonically with increasing Se concentration.
However, that of V changes with minimum at 40 at% Se. The nonmagnetic states of V, Co and Ni solutes have been discussed with Anderson model. According to this analysis, the changing trend of additional susceptibilities as a function of Se concentration is explained from the decreasing effect of N_d and the increasing effect of (U+4J)⁄Δ.
