MgB2: superconductivity and pressure effects
V. A. Ivanov, J. J. Betouras, F. M. Peeters
We present a Ginzburg-Landau theory for a two-band superconductor with emphasis on MgB. Experiments are proposed which lead to identification of the possible scenarios: wheth…

Raman scattering study of phonon and spin modes in (TMTSF)2PF6
Z. V. Popovic, V. A. Ivanov, O. P. Khoung +3
We have studied polarized Raman spectra of (TMTSF)2PF6 single crystals in the wide spectral and temperature range using different laser energies. We observed and assigned 23 Raman…

Superconductivity with angular dependent coupling: stripes, Coulomb repulsion and enhanced Tc
V. V. Moshchalkov, V. A. Ivanov
We have analysed the effect of intrinsic doping inhomogeneity and the presence of stripes in high-T_c superconductors on coupling λby using a simple analytically solvable model wit…
