Abstract

The periods of Gantmakher–Kaner oscillations for magnetic fields less than 1000 G and directed along the principle axes of gallium is reported. These oscillations were measured using a transmission technique at 1.74 MHz. The dependence of amplitude upon polarization of the RF magnetic field has enabled two of the observed periods to be identified with two small pieces of Fermi surface predicted by a recent theoretical model due to Reed. These pieces are Reed's sixth-band hole surface along T(6h), and the seventh-band electron surface along U(7e). The period which we observe for fields along the B direction in gallium, and which has its origin in Reed's 6h hole ellipsoid, is in excellent agreement with the period reported recently by Milligan and Castner using 9.2 GHz radiation.
