Galvanomagnetic properties and noise in a barely metallic film ofV2O3

Abstract

We have measured the magnetotransport properties of a strained metallic V 2 O 3 thin film. Most of the properties are similar to V 2 O 3 single crystals that have been submitted to a large pressure. In addition, the resistance noise analysis indicates that conductivity fluctuations are freezing out at T Ϸ 10 K. Examination of a range of measurements leads to the conclusion that spins-configuration fluctuations dominate in the lowtemperature regime.

High electronic conductivity in nanostructured materials based on lithium-iron-vanadate-phosphate glasses

“…In our case the conductivity increase is irreversible. Secondly, the MIT effect occurs in pure VO 2 at ca 340 K [28] and in V 2 O 3 at ca 160 K [30] or 150 K [31]. In this study we have not observed any discernible features on the temperature dependences of the electrical conductivity near 340 K (Figs.…”

Synthesis and characterization of V2O3 nanocrystals by plasma hydrogen reduction

“…The doping of a small amount of Al, Cr or W, Ti can shift the transition temperature to high or low region [8,[16][17][18][19][20]. This reversible structural transition makes V 2 O 3 a very attractive candidate for a wide variety of technological applications [12,16,[21][22][23][24][25][26].…”
