Electron motion and the Hall effect in monocrystalline zinc

Abstract

The Hall resistivity ρ21(B, T) observed in Zn when [Formula: see text] and [Formula: see text] has been measured in fields B = 0.1–2.0 T and at temperatures T = 1.7–680 K. Supporting measurements of the transverse magnetoresistance have also been made at 1.7 K. A qualitative analysis of ρ21(B, T) is given separately for the cases when the cyclotron motion is confined to an axial or to the basal plane. In the latter case, the discussion is supported by path integral calculations based upon model orbits chosen to imitate all the geometrical possibilities arising from magnetic breakdown between the monster and needle sheets. The results provide an explanation of the principal features shown by ρ21(B, T).
