Phase inverted Shubnikov-de Haas oscillation in bismuth
ABSTRACT Transverse magnetoresistance and Hall effect in slightly uncompensated bismuth single crystals have been measured at low temperatures. Contrary to the high purity bismuth, anomalous phenomena, i.e. perfect phase inversion and amplitude enhancement of the Shubnikov-de Haas oscillation in transverse magnetoresistance were observed. It was also found that the non-oscillatory part of the magnetoresistance does not obey the H2 law but tends to saturate with the increase of the magnetic field H. A phenomenological theory is proposed, which can explain these experimental results inclusively.
