ResumoAzbel'-Kaner cyclotron resonance has been studied at 22.9 GHz and 2\ifmmode^\circ\else\textdegree\fi{}K in the ${10\overline{1}0}$, ${11\overline{2}0}$, {0001}, and ${10\overline{1}1}$ planes of magnesium. Fifteen distinct mass series have been identified and their mass values determined as a function of the orientation of the magnetic field in the sample surface. Nearly all of the observed signals have been successfully assigned to the Fermi surface of Mg determined by Stark and his co-workers. Our results are in excellent agreement with their magnetoacoustic and de Haas-van Alphen measurements and their pseudopotential band-structure calculation except for the absence of cyclotron resonance signals from the "giant" orbit and the hexagonal grid of coupled orbits so prominent in the de Haas-van Alphen data. The absence of cyclotron resonance signals from these orbits confirms Moore's conclusion that cyclotron resonance signals will not be seen from orbits in the intermediate stage of magnetic breakdown.
