|Title:||Avalanchelike magnetic relaxation in the peak-effect regime of a Nb-O solid solution|
|Abstract:||An increase of the pinning of vortices near the upper critical field boundary, the peak effect (PE), is studied in a Nb-O solid solution by means of the magnetization measurements. The PE onset is understood as a disorder-induced transition between a relatively ordered vortex lattice and an entangled vortex state. It is found that a characteristic feature of the vortex state in the PE region is a relaxation occurring via a large size magnetization jump or avalanche. It is also found that the temperature and field-dependent time t(j)(H,T), at which the jump occurs, quasi diverges at the peak field H-p(T).|
