โฆ Synopsis
Magnetoreflection experiments have been performed on samples of pyrolytic, single crystal and kish graphite. Comparing the data for these samples we conclude that with a single set of band parameters the Slonczewski-Weiss-McClure band model adequately describes the magnetoreflection data for all three varieties of graphite. Furthermore, more precise values of the band parameters y,, and A are determined from the H point magnetoreflection resonances. It is also concluded that the introduction of a stacking fault parameter into the electronic energy band model as proposed by Tsukada and Uemura is not necessary for the interpretation of magnetoreflection data.
