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…
