Electron spin susceptibilities of the liquid binary alkali alloys
Properties of the conduction electron system in the liquid binary alkali metal alloys were investigated. Experimental values are given of the Knight shifts of both constituents of a binary alloy, when possible, for those alloys not previously studied. As the binary alloys of sodium, potassium, rubidium and cesium with one another are completely miscible in the liquid state, the entire concentration range for all alloys was covered. The Knight shifts were then interpreted to give the electron spin susceptibilities of those alkali metals for which the spin susceptibility has not yet been reported. These susceptibilities were then used to obtain experimental values of other interesting quantities. Measured values of the density of states at the Fermi surface for the pure metals were obtained. Finally these measured densities of states and the measured specific heats were combined to give measured values of the electron-phonon interaction contribution to the thermal effective mass of the electrons in the pure metals.
