Anomalous longitudinal Shubnikov-de Haas oscillation of bismuth which was found by the authors is confirmed by extending the experimental temperature range up to 40K. With the temperature rise, the oscillation amplitude increases remarkably at lower temperatures, saturates and decreases slowly at higher temperature. The effect is explained by considering two types of relaxation mechanisms of electron orbits, i.e., intra-Landau level and inter-Landau level scatterings due to phonons. Phonons responsible for the inter-level scatterings are less excited at lower temperature and give the observed anomalous effect. A numerical estimate has been presented. [ABSTRACT FROM AUTHOR] |
