Abstract
CrO 2 films were deposited on Al2O3 and TiO2 by high-pressure decomposition of CrO3. They are metallic, with a residual resistivity ρ0 in the range 0.2–10 μΩ m. The resistivity below Tc varies as ρ0+αT2+βT7/2 as expected for a correlated fully spin-polarized d band. At Tc the resistivity changes slope but the sign remains positive. There is a small negative magnetoresistance (∼−0.5%/ T) in a wide temperature range below Tc. Coercivity of the films varies according to the substrates from 7 mT for Al2O3 (110) to 15 mT for TiO2 (110).This publication has 17 references indexed in Scilit:
