Abstract
The theoretically predicted high spin polarization of half-metallic ferromagnets like CrO 2 and NiMnSb make them to promising materials for magnetoelectronic applications. Highly textured CrO 2 films have been prepared by chemical vapor deposition and molecular beam epitaxy. The temperature-dependent magnetotransport data has been correlated with electronic properties of CrO 2. Over a wide temperature range (150–330 K) the resistivity follows a T 2 behaviour, consistent with electron-electron scattering. Near the Curie temperature of CrO 2 no metal-insulator transition, a magnetoresistance of −7% ( B=9 T ) and an enhancement of the resistance due to electron-magnon scattering are observed.
