Observation of Leggett's collective mode in a multi-band MgB2 superconductor
G. Blumberg, A. Mialitsin, B. S. Dennis +3
We report observation of Leggett's collective mode in a multi-band MgB2 superconductor with T_c=39K arising from the fluctuations in the relative phase between two superconducting…
Multi-Gap Superconductivity in MgB2: Magneto-Raman Spectroscopy
G. Blumberg, A. Mialitsin, B. S. Dennis +2
Electronic Raman scattering studies on MgB2 single crystals as a function of excitation and polarization have revealed three distinct superconducting features: a clean gap below 37…
Manifestations of fine features of the density of states in the transport properties of KOs2O6
A. Akrap, E. Tutis, S. M. Kazakov +3
We performed high-pressure transport measurements on high-quality single crystals of KOs2O6, a beta-pyrochlore superconductor. While the resistivity at high temperatures might appr…
s-wave symmetry along the c-axis and s+d in-plane superconductivity in bulk YBa_2Cu_4O_8
R. Khasanov, A. Shengelaya, A. Bussmann-Holder +3
To clarify the order parameter symmetry of cuprates, the magnetic penetration depth was measured along the crystallographic directions , , and in single crystals of Y…
MgB2 single crystals substituted with Li and with Li-C: Structural and superconducting properties
J. Karpinski, N. Zhigadlo, S. Katrych +4
The effect of Li substitution for Mg and of Li-C co-substitution on the superconducting properties and crystal structure of MgB2 single crystals has been investigated. It has been…
