Cyclotron resonance (CR) measurements on a single crystal of PrSb have been performed at temperatures between 1.5 K and 20 K in the frequency range from 50 to 110 GHz. Three CR absorption lines are observed at low temperatures. For magnetic fields parallel to the [001] direction, the determined effective masses are 0.25m0, 0.3m0, and 0.53m0, respectively. In addition to “normal” CR, we have observed Doppler-shifted cyclotron resonance which shows nonlinear behavior on the frequency–field diagram.
