Reports from University of Antwerp Describe Recent Advances in Superconductivity (Optimizing mesoscopic two-band superconductors for observation of fractional vortex states)

By a News Reporter-Staff News Editor at Physics Week -- Current study results on Superconductivity have been published. According to news originating from Antwerp, Belgium, by VerticalNews correspondents, research stated, "Using the two-component Ginzburg-Landau model, we investigate the effect of sample size and magnitude and homogeneity of external magnetic field on the stability of fractional vortex states in a mesoscopic two-band superconducting disk."

Our news journalists obtained a quote from the research from the University of Antwerp, "We found that each fractional state has a preferable sample size, for which the range of applied field in which the state is stable is pronouncedly large. Vice versa, there exists an optimal magnitude of applied field for which a large range of possible sample radii will support the considered fractional state."

According to the news editors, the research concluded: "Finally, we show that the stability of fractional states can be enhanced even further by magnetic nanostructuring of the sample, i.e. by suitably chosen geometrical parameters and magnetic moment of a ferromagnetic dot placed on top of the superconducting disk."
