✦ Synopsis

Thermodynamically stable vortex-antivortex configurations have been found in mesoscopic type I superconducting equilateral triangles. The revealed effect is explained by two factors: (i) vortex confinement in mesoscopic triangles and (ii) appearance of the vortex-antivortex repulsion in mesoscopic type I superconductor triangles in the vicinity of the dual point. The stability of the obtained solutions is examined as a function of material and external parameters--the Ginzburg-Landau parameter j and temperature--as well as a function of a distortion of the sampleÕs shape.

We have studied vortex expulsion processes in a superconducting disk with a multi-terminal Hall sensor. Various combinations of these terminals enabled us to obtain an angular dependence of magnetization in the disk. The resolution of p/4 allowed us to identify three vortices. With a decrease in mag

In this paper we apply the time dependent Ginzburg-Landau (TDGL) equations to the study of thin superconducting films of variable surfaces in the presence of an external applied magnetic field. We have made a systematic investigation of both the lower and upper critical fields as a function of the t
