SELF-CONSISTENT CALCULATIONS OF THE ZEEMAN SPLITTING IN METALS

The electronic structure of metals in an external magnetic field has b een investigated by means of a version of the linear-muffin-tin-orbita l method, in which the magnetic field, exchange and correlation effect s, and spin-orbit coupling have been included in the self-consistent i terations. The Zeeman splitting of cyclotron orbits has been calculate d and compared to de Haas-van Alphen experiments for the alkali metals , the noble metals, and the platinum group metals. Also the paramagnet ic susceptibilities have been calculated. Particular attention is paid to the importance of the orbital magnetic moment. A detailed treatmen t of palladium is included in order to evaluate the calculational meth od. Detailed comparisons with experimental data have been made whereve r possible. In some cases the agreement between theory and experiment is very good. Possible reasons for lacking agreement are discussed and suggestions for improved theoretical procedures are made.
