✦ Synopsis

scattering at the boundaries is one of the causes and possibly the dominant one for the observed negative magnetoresistance.

161. Non-linear conduction in graphite at high electric field S. Mizushima (School of En~~e~~g, K&o ~n~ve~~, Tokyo, &pan). Saturation of current in graphite at high electric field was found, which is considered to be caused by the electron-phonon interaction, along with concomittant phenomena such as current oscillation and light emission, which are supposedly results of current pinch. 16% The effect of applied current on electrical conduction in hot-pressed pyrolytic graphite before and after neutron irradiation J. D. Cooper, M. L. Yeoman and D. A. Young (Department of ChemzCal Engineering and Chemical Technoes, Im~al CoUege, Loon, S.W. 7, U.K.

). The application of hydrostatic pressure to graphite produces a large pressure coefficient of conduction normal to the basal planes. In this direction the pressure coefficient is almost independent of temperature. Parallel to the basal planes, however, the pressure coefficient depends markedly on temperature.
