GALVANOMAGNETIC EFFECTS IN GRAPHITE

A summary is given of recent work on galvanomagnetic effects in highly oriented pyrolytic graphite with current flow in the basal planes and magnetic field parallel to the c-axis. Experimental studies over a wide range of field are considered (0.001-23T) including the effect of fast neutron irradiation (0-2.9×1017 nvt (E > 1 MeV)). Theoretically, the effects of the variation of carrier properties along the zone edge, and trigonal warping of the constant energy surfaces are considered, and comparison made with predictions of the simple two band model usually used to describe galvanomagnetic properties. © 1979.
