Magnetoacoustic Attenuation in Single Crystal Beryllium.
Abstract
Magnetoacoustic quantum oscillations (MAQO's) in beryllium have been observed in magnetic fields to 100 kOe, and at sonic frequencies from 200 MHz to 1.85 GHz, at 1 K. Areas of extremal cross sections of the Fermi surface of Be were found to be in agreement with de Haas - van Alphen data reported by others, and with existing pseudopotential theory. Magnetoacoustic geometric resonances which give caliper dimensions of the Fermi surface, were observed at frequencies from 500 MHz to 1.85 GHz with longitudinal sound and at 1 K. Caliper dimensions of the coronet in the (1,0,-1,0) direction of the basal plane are in good agreement with theory.
