Abstract

Measurements of the galvanomagnetic properties of highly-oriented pyrolytic graphite have been made in the field range 0.001-1.5 T at 298, 77.4 and 4.2 K, with selected measurements to higher fields and ∼1.2K. Specimens of graphite were chosen with properties approximating those of purified natural crystals (single crystals) of graphite. Attention is drawn to differences in the properties of these materials. The data are analyzed with particular emphasis on the density of free carriers and its dependence on temperature, since earlier work had shown that experimental results were appreciably different from theoretical predictions.
