Energy bands and fermi surface of the intermetallic compound YZn

Energy bands of the simple cubic intermetallic compound YZn have been calculated by using the APW method. The crystal potential (constructed in the muffin-tin approximation from overlapping atomic charge densities and full Slater exchange) was adjusted slightly and a larger set of basis functions was used than in a previous calculation. The resulting Fermi surface is exhibited and shown to be fully in agreement with the results of a recent de Haas-van Alphen experiment.
