✦ Synopsis

Possible scaling rules for the magnetoresistance and magnetoconductance of graphite are ex,tmined experimentally and theoretically within the simple two band model. It is shown that such rules are not applicable to graphite. The influences of dispersion of carrier properties along the Brillouin Zone edge and trigonal warpmg of the constant energy surfaces are briefly discussed. These results are used to assess empirical formulae for estimating the mean carrier mobility in the basal planes and their rignificance.
