Witryna8 maj 2024 · Here, we show that the number and the shape of Shiba states are correlated to the spin-polarized atomic orbitals of the impurity, hybridized with the superconductor. Using scanning tunnelling... 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.
