Vortex-like excitations in a non-superconducting single-layer compound BiSrCuO single crystal in high magnetic fields
S. I. Vedeneev, D. K. Maude
The in-plane and the out-of-plane magneto-transport in magnetic fields up to 28 T has been investigated in high quality non-superconducting (down to 20 mK)…
Optical sum rule in metals with a strong interaction
A. E. Karakozov, E. G. Maksimov
The restricted optical sum rule and its dependence on the temperature, a superconducting gap and the cutoff energy have been investigated. As known this sum rule depends on the cut…
Quasiparticle density of states in BiSrCaCuO single crystals probed using tunneling spectroscopy at ultra-low temperatures in high magnetic fields
S. I. Vedeneev, D. K. Maude
Break-junction tunneling spectroscopy at temperatures 30-50 mK in high magnetic field is used to directly probe the quasiparticle density of states within the energy gap in a singl…
The effect of magnetic impurities in a two-band superconductor: A point-contact study of Mn-substituted MgB2 single crystals
R. S. Gonnelli, D. Daghero, G. A. Ummarino +8
We present the first results of directional point-contact measurements in Mg_{1-x}Mn_{x}B_2 single crystals, with x up to 0.015 and bulk T_c down to 13.3 K. The order parameters De…
The mechanism of hole carrier generation and the nature of pseudogap- and 60K-phases in YBCO
K. V. Mitsen, O. M. Ivanenko
In the framework of the model assuming the formation of NUC on the pairs of Cu ions in CuO plane the mechanism of hole carrier generation is considered and the interpretation…
Critical temperature and giant isotope effect in presence of paramagnons
O. V. Dolgov, I. I. Mazin, A. A. Golubov +2
We reconsider the long-standing problem of the effect of spin fluctuations on the critical temperature and isotope effect in a phonon-mediated superconductor. Although the general…
Heat transport in Bi_{2+x}Sr_{2-x}CuO_{6+δ}: departure from the Wiedemann-Franz law in the vicinity of the metal-insulator transition
Cyril Proust, Kamran Behnia, Romain Bel +2
We present a study of heat transport in the cuprate superconductor Bi_{2+x}Sr_{2-x}CuO_{6+δ} at subkelvin temperatures and in magnetic fields as high as 25T. In several samples wit…
