摘要: Magnetic properties of Pd metal and Pd-Rh Pd-Ag alloys with the addition Co Fe atoms are analyzed by itinerant model 4d-electrons. It is assumed that dissolved have localized magnetic moments distributed at random. Spin quantum number moment atom a molecular field coefficient between 4d-electron estimated from comparison our theory experiments. The values spin for as 1 3/2 in these alloys. Making use value among 4d-electrons density states curve, which were obtained before metal, composition dependences Curie temperature paramagnetic susceptibility numerically calculated. results can explain almost all experiments satisfactorily.
