Raman scattering from the CaC6 superconductor in the presence of disorder
A. Mialitsin, J. S. Kim, R. K. Kremer +1
Polarized Raman scattering has been performed on CaC6 superconductor. We identify two of the three Raman active Eg phonon modes at 440 and 1508 cm-1 expected for the R-3m space gro…
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…
Anharmonicity and self-energy effects of the E2g phonon in MgB2
A. Mialitsin, B. S. Dennis, N. D. Zhigadlo +2
We present a Raman scattering study of the E2g phonon anharmonicity and of superconductivity induced self-energy effects in MgB2 single crystals. We show that anharmonic two phonon…
