Combined Resonances in Hot-Electron Magnetophonon Oscillations in InSb

Abstract
A full series of combined cyclotron- and spin-resonance transitions is observed in magnetophonon oscillations in n-InSb under hot-electron conditions. These originate from the emission of LO phonons. Probabilities of combined resonances induced by polar and nonpolar coupling with optical phonons are calculated for the spin-orbit interaction mechanism.
