Doppler-shifted cyclotron resonance and doppleron-phonon resonance in molybdenum
Galkin A.A. , Tsymbal L.T., Grishin A.M., Butenko T.F.
We investigated theoretically and experimentally resonance absorption of transverse ultrasound waves in molybdenum single crystals in a magnetic field parallel to the wave vector of the sound. In addition to several series of Doppler-shifted acoustic cyclotron resonance, we observed a resonant absorption maximum due to excitation of a doppleron in the metal.
