Abstract
The electrical transport properties of single phase compositions in the system (Fe2O3) x (V2O5)1−x , where 0<x<0·25, have been investigated and discussed. The compounds have been found to exhibit thermally activated hopping conduction, where the charge carriers are electrons localised at V4+ (3d 1) centres. The Fe3+ ions appear to occupy interstitial as well as substitutional positions in the V2O5 lattice.
