Resistivity of the amorphous OsO2 wasless than 631023 V cm at 80 K, and it was almost temperature independent, but the temperature coefficient ofresistivity was negative. The Hall coefficient of the amorphous OsO2 increased with temperature, and wassaturated at around 220 K. Temperature dependence of the Hall mobility was proportional to T3/2, and itimplies that the scattering of charged carriers by ionized atoms is dominant below 220 K.}, pages = {11125--11127}, title = {Electronic structure and electrical properties of amorphous OsO2}, volume = {59}, year = {1999}, yomi = {コヒキ, シゲミ} }
