Abstract
V2O3 powder and film were prepared by the reduction of sol–gel-synthesized V2O5. The V2O3 single phase was synthesized by reduction above 500°C for 2 h in hydrogen atmosphere. X-ray diffraction measurements revealed that the films were distorted by the substrate and that the antiferromagnetic insulator-metal (AFI-M) transition observed in resistivity temperature curves of the films was broader than those of powders. It was concluded that the broader transition was caused by film strain.Keywords
