Origin of peak-effect in the second type superconductors

Creators

Description

The macroscopic pinning force peak appears near Hsub(C2) when elastic interactions between vortexes appreciably decrease their connection with a concentrated enough system of relatively weak pinning centers in the middle magnetic field region (where effective moduls of the flux line lattice have a maximum value). In such a case the peak effect results from 'melting' of the flux line lattice at B → Hsub(C2). (orig.)

Abstract (German)

Der makroskopische Pinning-Kraft-Peak erscheint nahe bei Hsub(C2), wenn elastische Wechselwirkungen zwischen den Wirbeln ihre Verbindung mit einem ausreichend konzentrierten System relativ schwacher Pinning-Zentren im mittleren Be → Hsub(C2) Magnetfeldes (wo effektive Moduln des Flussliniengitters ein Maximum haben) spuerbar mindern. In einem solchen Fall resultiert der Peakeffekt aus dem 'Schmelzen' des Flussliniengitters bei B → Hsub(C2). (orig.)
