文摘

Influence of oxide matrix on electron transport in (FeCoZr)x(Al2O3)1-x nanocomposite films. Electron transport in nanocomposites produced by ion-beam sputtering was studied. Addition of oxygen to sputtering atmosphere suppresses Mott hopping conductivity. This effect is determined by oxygen-induced reduction of alumina matrix defectiveness.
