Magnetic feedback and quantum oscillations in metals Van Schyndel, André John
Abstract
A feedback technique is presented for the reduction of the Shoenberg magnetic interaction in metals. The method allows the spin splitting parameter g[sub c] for extremal orbits on the Fermi surface to be obtained from de Haas-van Alphen measurements, now essentially free from the oft-times severe distortions resulting from magnetic interaction. The feedback technique also offers several advantageous side effects, the most important one being a simple and reliable method for determining absolute amplitudes of de Haas-van Alphen oscillations. Explicit formulae are derived showing the dependence of several key observable quantities on the amount of magnetic feedback, and these formulae are found to be in good agreement with experiment. The technique is applied to the determination of g[sub c] for the [110] γ oscillations in Pb.
