Size-effect oscillations of the longitudinal magnetoresistance of thin cylindrical bismuth single crystals
Brandt N.B., Gitsu D.V., Nikolaeva A.A., Ponomarev Ya.G.
Longitudinal-magnetoresistance oscillations that are equidistant in the field and decrease in amplitude have been observed in weak magnetic fields in cylindrical bismuth single-crystal whiskers 0.2-0.8 μ thick. These oscillations are apparently caused by sample-dimension induced periodic truncation of the orbits of the electrons corresponding to quantized non-extremal sections of the Fermi surface.
