Low Temperature Resistivity, Magnetic Susceptibility, and Superconducting Transition Temperature in Lanthanum Containing Rare-Earth Impurities

摘要: The resistivities and the magnetic susceptibilities of lanthanum containing small amounts other rare-earth metals have been measured at low temperatures. Resistance minima found about 6.5°K in fcc La-Ce alloys 5.8°K hcp alloys. temperature which resistance minimum occurs is independent concentration Ce. Any has not with solutes than observed resistivity all contains a term proportional to log T accordance recent theories on s - d or f due Kondo others. La-Ce, La-Pr, La-Nd are inconsistent resistive behaviors these effective exchange integrals for various calculated from data compared those change superconducting transition La added metals. agreement between...
