摘要:

Electrical resistivity, magnetoresistance, ac‐susceptibility, and dc‐magnetization have been measured in a few Co‐rich metallic glasses containing Cr/Mn. These alloys have large electrical resistivity (200 &mgr;&OHgr;cm) and show resistivity minima. The addition of Cr/Mn takes the minimum beyond 200 K. We have observed three distinct temperature regions where the conductivity goes as &sqrt;T, T and &sqrt;T as T increases, in agreement with the predictions of the theories of electron localization and electron‐electron interaction. The analysis holds irrespective of the magnetic state of the alloys, viz, mixed ferro‐spin‐glass, ferromagnetic or nearly paramagnetic. Also ferromagnetism does not seem to destroy electron localization.
