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.
