Peak Effect in Type II Superconductors: Yield Point of the Fluxon Lattice

Abstract: The complicated current-voltage (flux flow) curves obtained from type 11 superconductors which show the peak effect are compared to the stress-strain curves of crystalline materials in which plastic flow a t low stresses is prevented by pinning of dislocations. It is suggested that the unstable step in the current-voltage characteristic is the result of "yield" and subsequent shearing of the fluxon lattice by dislocation motion.Die komplizierten Strom-Spannungs-(StromfluB-)Kurven, die an Typ-11-Supraleitern er… Show more

“…Pinning centres can, therefore, be expected to interact with defects with about twice the force that they exert on a single vortex in the perfect lattice. Chang et al (1969) appear to be the ®rst to have interpreted voltage current characteristics in terms of yield and dislocation motion in the vortex lattice.…”
