摘要：
Cyclotron resonance (CR) measurements on a single crystal of LaSb have been performed at temperatures between 1.6 and 40 K in the frequency range from 50 to 190 GHz. In addition to "normal" CR, we have observed two anomalous absorption lines that show nonlinear behavior on the frequency-field diagram. The nonlinear behavior is explained by the Doppler-shifted cyclotron resonance coupled with a magnetoplasma wave (Alfven wave) propagating in the quite high-quality single crystal of LaSb.
