Singularities of Shubnikov-de Haas effect in thin antimony plates
Gaidukov Yu.P., Golyamina E.M.
We investigate the galvanomagnetic properties of platelike single crystals (whiskers) of antimony. Two types of resistance oscillations are observed. The first is observed in strong magnetic fields 2 r < d and constitutes the Shubnikov-de Haas (SdH) effect on the extremal section of the hole Fermi surface (r is the radius of the orbit). The second is observed in weak fields 2r> d, and analysis of the experimental results show that it is the SdH effect on the same extremal section truncated by the surfaces of the sample. This phenomenon was predicted by Kosevich and Lifshitz in 1955.
