Magnetic field dependence of the oxygen isotope effect on the magnetic penetration depth in hole-doped cuprate superconductors
R. Khasanov, A. Shengelaya, D Di Castro +7
The magnetic field dependence of the oxygen-isotope (^{16}O/^{18}O) effect (OIE) on the in-plane magnetic field penetration depth λ_{ab} was studied in the hole-doped high-temperat…
Coexistence of superconductivity and incoherence in quasi 1D chains
R. Khasanov, T. Kondo, J. Schmalian +7
The dimensionality of a correlated many-body system has a large impact on its electronic properties. When electrons are confined to one-dimensional chains of atoms their behavior i…
Dual character of the electronic structure in YBa2Cu4O8: conduction bands of CuO2 planes and CuO chains
T. Kondo, R. Khasanov, J. Karpinski +10
We use microprobe Angle-Resolved Photoemission Spectroscopy (muARPES) to separately investigate the electronic properties of CuO2 planes and CuO chains in the high temperature supe…
Thermal conductivity of Al-doped MgB2: Impurity scattering and the validity of the Wiedemann-Franz law
A. V. Sologubenko, N. D. Zhigadlo, J. Karpinski +1
We report data on the thermal conductivity K(T,H) along the basal plane of the hexagonal crystal structure of superconducting Mg{1-y}Al{y}B2 with y=0.02 and 0.07 at temperatures be…
Point-contact Andreev-reflection spectroscopy in segregation-free Mg_{1-x}Al_{x}B_2 single crystals up to x=0.32
D. Daghero, D. Delaude, A. Calzolari +7
We present new results of point-contact Andreev-reflection (PCAR) spectroscopy in single-phase Mg_{1-x}Al_{x}B_{2} single crystals with x up to 0.32. Fitting the conductance curves…
Correlation between oxygen isotope effects on the transition temperature and the magnetic penetration depth in high-temperature superconductors close to optimal doping
R. Khasanov, A. Shengelaya, K. Conder +4
The oxygen-isotope (^{16}O/^{18}O) effect (OIE) on the in-plane magnetic penetration depth λ_{ab}(0) in optimally-doped YBa_2Cu_3O_{7-δ} and La_{1.85}Sr_{0.15}CuO_4, and in slightl…
