Galvanomagnetic Properties of Graphite at Low Temperatures

Abstract

A diagonal component of the magnetoconductivity tensor in graphite at 0°K is calculated as a function of magnetic field from 10⁴ to 2.50×10⁴ gauss by the use of the Slonczewski and Weiss model and the quantum theory of galvanomagnetic phenomena by Adams and Holstein. The Fermi level is calculated in the region of field intensity from 10⁴ to 6.4×10⁴ gauss. The theory is limited to the case 0°K but it is consistent with the features of the measurement made by Soule, McClure and Smith at 1.26°K qualitatively. The scattering potential used in this study is a quasi-delta function with a finite force range of 6°A. For simplicity the trigonal symmetry of the bands (γ₃) is disregarded.
