de Haas-van Alpen Effect and Azbel'-Kraner Cyclotron Resonance Studies for Mercury

Abstract

<p>Previous studies of the mercury Fermi surface by Azbel'-Kaner cyclotron resonance and the de Haas-van Alphen effect have been extended and clarified and several new orbits have been observed. The results are in qualitative agreement with the topologies of current models of the Fermi surface.</p> <p>Measurements of the temperature dependence of the cyclotron effective mass and the collision relaxation time for an electron lens orbit have provided new experimental evidence for electron-phonon mass enhancement and the influence of Umklapp processes in determining the relaxation time.</p> <p>Several methods for orienting mercury crystals within the experimental apparatus have been developed.</p>
