Impurity superconductor
Witryna21 wrz 2024 · Interplay between impurities and superconductors is the focus of many studies [].Bound states near magnetic impurities in the conventional s-wave superconductor are an example of such interplay. This behavior was proposed by Yu [], Shiba [] and Rusinov [] in the 1960s.In those pioneering papers, authors describe the … Witryna2 mar 2024 · We present a study of the superconducting properties of the candidate topological superconductor Ti3Sb. Electrical transport measurements show zero resistance with a T c,onset of ≈5.9 K with a transition width ΔT c≈ 0.6 K. The superconducting phase boundaries as derived from magnetotransport and magnetic …

WitrynaSuperconductivity is the ability of certain materials to conduct electric current with practically zero resistance . This capacity produces interesting and potentially useful … Witryna1 History. It was known well before the Bardeen, Cooper, and Schrieffer (BCS) theory of superconductivity that magnetic impurities in superconducting materials could cause large depressions in superconducting transition temperatures. But the first experiments where the systematics of the depression of superconductivity by magnetic …

We investigate the role of the Bloch functions and superconducting gap symmetries on the formation and properties of impurity-induced resonances in a 2D superconductor, and elucidate their … WitrynaTo understand the impurity effect on T c in FeAs superconductors, we analyze a simple two-band BCS model with a repulsive interband interaction. The realized fully gapped superconducting state with sign reversal, which is predicted by spin fluctuation theories in this compound, is suppressed by impurities due to the interband hopping of Cooper …
WitrynaIt is well-known that magnetic impurities compete with superconductivity in a manner analogous to the Meissner effect: if the concentration of impurities is large, enough bound states can open up in the gap that the gap disappears, destroying superconductivity.
As the electron doping of RbxC60 deviates slightly from half-filling, subsurface tetragonal Rb vacancies emerge as dark windmills as x < 3, whereas excess K adatoms appear and occupy the octahedral sites as x > 3.
