Scanning Tunneling Spectroscopy in the Superconducting State and Vortex Cores of the beta-pyrochlore KOs2O6
C. Dubois, G. Santi, I. Cuttat +8
We performed the first scanning tunneling spectroscopy measurements on the pyrochlore superconductor KOs2O6 (Tc = 9.6 K) in both zero magnetic field and the vortex state at several…
Node-like excitations in superconducting PbMo6S8 probed by scanning tunneling spectroscopy
C. Dubois, A. P. Petrovic, G. Santi +6
We present the first scanning tunneling spectroscopy study on the Chevrel phase PbMo6S8, an extreme type II superconductor with a coherence length only slightly larger than in high…
First Scanning Tunnelling Spectroscopy on Bi2Sr2Ca2Cu3O10 (Bi2223) single crystals
Martin Kugler, Giorgio Levy, Enrico Giannini +4
We report the first low temperature scanning tunnelling microscopy and spectroscopy study of high quality Bi2223 crystals. We present atomic resolution and show spectroscopic data…
Four-fold structure of vortex core states in Bi2Sr2CaCu2O8 (Bi2212)
Giorgio Levy, Martin Kugler, Alfred A. Manuel +2
We present a detailed study of vortex core spectroscopy in slightly overdoped Bi2Sr2CaCu2O8 using a low temperature scanning tunneling microscope. Inside the vortex core we observe…
Experimental evidence for fast cluster formation of chain oxygen vacancies in YBa2Cu3O7-d being at the origin of the fishtail anomaly
Andreas Erb, Alfred A. Manuel, Marc Dhalle +13
We report on three different and complementary measurements, namely magnetisation measurements, positron annihilation spectroscopy and NMR measurements, which give evidence that th…
Hole depletion and localization due to disorder in insulating PrBa2Cu3O7-d: a Compton scattering study
Abhay Shukla, Bernardo Barbiellini, Andreas Erb +4
The (mostly) insulating behaviour of PrBa2Cu3O7-d is still unexplained and even more interesting since the occasional appearance of superconductivity in this material. Since YBa2Cu…
