Abstract
The surface conductance under anomalous skin effect conditions of polycrystalline samples of the hexagonal divalent metals magnesium, zinc and cadmium is measured and used to determine their Fermi surface areas. The results for zinc and cadmium are in good agreement with the theoretical values, which are estimated in the nearly-free electron approximation for recently proposed models of their Fermi surfaces. For magnesium the Fermi energy is regarded as a variable parameter, and the experimental value for the area provides a sensitive measure of its position relative to the calculated energy levels at points of high symmetry in the Brillouin zone. The area for each metal when combined with the d.c. conductivity and the electronic specific heat also yields average values of the mean free path and Fermi velocity.
