Nearly-Free-Electron Susceptibility of Liquid Metals

Abstract

The magnetic susceptibility of a liquid metal is calculated to second order in the electron-ion potential. The result is evaluated for a number of metals, and shows, generally, a small deviation from the free-electron susceptibility which can be positive or negative. When electron correlations are also taken into account, the theory yields liquid-metal susceptibilities and changes in susceptibility on melting roughly comparable to experiment.
