Specific heat of MgB_2 after irradiation
Yuxing Wang, Frederic Bouquet, Ilya Sheikin +6
We studied the effect of disorder on the superconducting properties of polycrystalline MgB_2 by specific-heat measurements. In the pristine state, these measurements give a bulk co…
Observation of an unconventional metal-insulator transition in overdoped CuO_2 compounds
F. Venturini, M. Opel, T. P. Devereaux +7
The electron dynamics in the normal state of BiSrCaCuO is studied by inelastic light scattering over a wide range of doping. A strong anisotropy of the electron…
Doping dependence of the electronic Raman spectra in cuprates
F. Venturini, M. Opel, R. Hackl +3
We report electronic Raman scattering measurements on BiSr(YCa)CuO single crystals at different doping levels. The dependence of the spectra on dopi…
Unusual dependence of vortex core states on the superconducting gap in BiSrCaCuO
B. W. Hoogenboom, K. Kadowaki, B. Revaz +3
We present a scanning tunneling spectroscopy study on quasiparticle states in vortex cores in BiSrCaCuO. The energy of the observed vortex core states shows an…
Direct Observation and Anisotropy of the Contribution of Gap nodes in the Low Temperature Specific Heat of YBa_2Cu_3O_7
Yuxing Wang, Bernard Revaz, Andreas Erb +1
The specific heat due to line nodes in the superconducting gap of YBa2Cu3O7 has been obscured up to now by magnetic terms of extrinsic origin, even for high quality crystals. We re…
Shape and Motion of Vortex Cores in Bi_2Sr_2CaCu_2O_{8+δ}
B. W. Hoogenboom, M. Kugler, B. Revaz +3
We present a detailed study on the behaviour of vortex cores in Bi_2Sr_2CaCu_2O_{8+δ} using scanning tunneling spectroscopy. The very irregular distribution and shape of the vortex…
Carrier relaxation, pseudogap, and superconducting gap in high-Tc cuprates: A Raman scattering study
M. Opel, R. Nemetschek, C. Hoffmann +9
We describe results of electronic Raman-scattering experiments in differently doped single crystals of Y-123 and Bi-2212. The comparison of AF insulating and metallic samples sugge…
Superconducting Gap and Pseudogap in Bi-2212
Matthias Opel, Francesca Venturini, Rudi Hackl +2
We present results of Raman scattering experiments in differently doped Bi-2212 single crystals. Below Tc the spectra show pair-breaking features in the whole doping range. The low…
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…
Observation of d-wave scaling relations in the mixed-state specific heat of YBa2Cu3O7
B. Revaz, J. -Y. Genoud, A. Junod +2
The low temperature specific heat C(B,T) of an YBa2Cu3O7.00 single crystal is measured from 1.2 to 10 K in magnetic fields up to 14 T. The anisotropic component Caniso(T,B)=C(T,B//…
