Abstract
We report microwave absorption measurements as a function of temperature (from 290 to 125 K) and magnetic field (from 0 to 0.3 T) in mm-thick parallelepipeds of sintered V2O3 and V2O3 containing micron-size Fe precipitates. As before, it turns out that near the metal-insulator (MI) transition, the loss exhibits a sharp peak as a function of temperature. On application of a magnetic field, the peak temperature for (V2O3+Fe) changes by a few kelvin, causing a giant magnetoimpedance ( ≈ 200% in 0.1 T field) in the neighborhood of the MI transition.
