The Hall coefficient, magnetoresistance and electrical resiativity of an extremely hard carbon, namely glassy carbon developed by the Tokai Electrode Mfg. Company, were investigated as function of heat-treatment temperature from loo0 to 3200Β°C at three ambient temperatures 20, 77 and 300Β°K. The rela
