Multiple doppleron-phonon resonances in indium
Abstract
Magnetic field dependences of absorption and phase velocity of circularly polarized ultrasonic waves were studied in super pure crystal of indium at the temperatures 1.28–4.2 K. Geometry of experiment corresponded to acoustic analogy of the Faraday effect. Multiple doppleron-phonon resonances were observed, as well as sharp peaks of Doppler-shifted acoustic cyclotron resonance and ultrasonic wave-field transport. (© 2004 WILEY-VCH Verlag GmbH & Co.
