Crystal growth, characterization and advanced study of the noncentrosymmetric superconductor MoAlC
N. D. Zhigadlo, D. Logvinovich, R. S. Gonnelli +2
We report on the first successful growth of single crystals of the noncentrosymmetric superconductor MoAlC obtained by means of a cubic-anvil, high-pressure and high-temper…
The Josephson current in Fe-based superconducting junctions: theory and experiment
A. V. Burmistrova, I. A. Devyatov, A. A. Golubov +8
We present theory of dc Josephson effect in contacts between Fe-based and spin-singlet -wave superconductors. The method is based on the calculation of temperature Green's funct…
The order-parameter symmetry and Fermi surface topology of 122 Fe-based superconductors: a point-contact Andreev-reflection study
R. S. Gonnelli, M. Tortello, D. Daghero +8
We report on the results of directional point-contact Andreev-reflection (PCAR) measurements in Ba(Fe_{1-x}Co_x)2As2 single crystals and epitaxial c-axis oriented films with x = 0.…
Effects of isoelectronic Ru substitution at the Fe site on the energy gaps of optimally F-doped SmFeAsO
D. Daghero, M. Tortello, G. A. Ummarino +5
We studied the effects of isoelectronic Ru substitution at the Fe site on the energy gaps of optimally F-doped SmFeAsO by means of point-contact Andreev reflection spectroscopy. Th…
Multigap superconductivity and strong electron-boson coupling in Fe-based superconductors: A point-contact Andreev-reflection study of Ba(Fe1-xCox)2As2 single crystals
M. Tortello, D. Daghero, G. A. Ummarino +5
Directional point-contact Andreev-reflection (PCAR) measurements in Ba(Fe1-xCox)2As2 single crystals (Tc=24.5 K) indicate the presence of two superconducting gaps with no line node…
Point-contact Andreev-reflection spectroscopy in ReFeAsO_{1-x}F_x (Re = La, Sm): Possible evidence for two nodeless gaps
R. S. Gonnelli, D. Daghero, M. Tortello +6
A deep understanding of the character of superconductivity in the recently discovered Fe-based oxypnictides ReFeAsO1-xFx (Re = rare-earth) necessarily requires the determination of…
