The mesoscopic one-dimensional magnetic texture caused by small Zeeman coupling in a p-wave superconductor in the magnetic field is found. The field orientation is opposite on the two sides of the texture and the magnitude can be even smaller than H-c1. The texture is not built from various singular topological defects, like vortices, as previously found in the simplest three-component Ginzburg-Landau model of superconductors.

The relaxation dynamics of a quenched normal spot in type-II superconductor is considered analytically and numerically. Various instabilities accompanying recovery of superconductivity are considered. Relaxation of the normal spot starts with appearance of a microscopic instability triggering the creation of the vortex clusters. (C) 2004 Elsevier B.V. All rights reserved.
