Linear and Field-Independent Relation between Vortex Core State Energy and Gap in Bi₂Sr₂CaCu₂O_8+δ

ments, completely automated, allows one to perform a complete set of measurements in two temperature runs without changing the sample holder and contacts: in the first run, an

The doping dependence amounts essentially to an energy scaling of the tunneling spectra, with a quasiparticle gap that is reduced with increasing oxygen concentration..

The striking correspondence of the vortex core spectra with the normal state pseudogap, the similarity of the low lying excitations inside and outside the vortex cores, as well as

In summary, we have shown that the model by Tallon and Williams [1], although reflecting the smooth evolution of the pseudogap into the superconducting gap at T c in un- derdoped

In Bi 2 Sr 2 CaCu 2 O 8+ x (Bi-2212) round wires, the precursor powders are embedded in a Ag matrix without any diffusion barrier, and elemental diffusion from the

However, the collective U may be higher than the pinning barriers for the individual vortex movements observed in our experiments. Thus, in order to find a lower bound for the

Scanning Tunneling Spectroscopy of Bi 2 Sr 2 CuO 6+δ : New Evidence for the Common Origin of the Pseudogap and Superconductivity.. KUGLER, Martin,

In conclusion, we have performed scanning tunneling spectroscopy experiments on high quality Sr 2 RuO 4 crystals in the superconducting state, which have allowed the direct
