Critical pressure effects in PdNi alloys

摘要: The magnetic properties such as Curie temperatures, spontaneous magnetizations, paramagnetic susceptibilities and their pressure derivatives of PdNi alloys with nickel concentrations below 15% have been measured. All these (from our measurements well from previously published measured values for up to 40%) are described in a local model coupling between moments through the palladium matrix. From concentration dependence temperature its variation authors derived exchange integral localized d electrons derivative agreement found case PdFe PdCo alloys. follow Curie-Weiss law. There exist ranges where magnetization vary proportionally concentration.
