A POSSIBLE EXPLANATION FOR THE NEGATIVE MAGNETO-RESISTANCE EFFECT IN THE RAPIDLY COOLED Al-Si ALLOYS
|
Abstract:
The analysis of the present letter shows that the negative magneto-resistance effect, observed by Guan Wei-yan et al. in rapidly cooled Al-Si alloys, is nothing but the longitudinal peak effect in films of type II superconductors displayed in the form of R-H3 curves. Based on the flux-line-cutting model, a possible explanation for this ef-fect is proposed.
