Journal ArticleDOI
Extended s± scenario for the nuclear spin-lattice relaxation rate in superconducting pnictides
TL;DR: In this article, the authors show that the lack of a coherence peak is fully consistent with the previously proposed nodeless extended s±-wave symmetry of the order parameter (whether in the clean or dirty limit) and that the low-temperature power-law behavior can be also explained in the framework of the same model but requires going beyond the Born limit.
Journal ArticleDOI
Josephson Effect due to Odd-Frequency Pairs in Diffusive Half Metals
TL;DR: The spin-flip scattering at the junction interfaces opens the Josephson channel of the odd-frequency spin-triplet Cooper pairs, and the local density of states in a half metal has a large peak at the Fermi energy.
Journal ArticleDOI
Specific heat measurements of Ba0.68 K0.32 Fe2 As2 single crystals: evidence for a multiband strong-coupling superconducting state
P. Popovich,Alexander Boris,Alexander Boris,Oleg V. Dolgov,Alexandre Avraamovitch Golubov,Dunlu Sun,Chengtian Lin,R. K. Kremer,Bernhard Keimer +8 more
TL;DR: It is shown that an Eliashberg model with two hole and two electron bands gives the correct values of Tc, the superconducting gaps, and the free-energy difference.
Journal ArticleDOI
Proximity effect in superconductor-insulator-superconductor Josephson tunnel junctions: Theory and experiment.
Alexandre Avraamovitch Golubov,Evert Pieter Houwman,J.G. Gijsbertsen,Vladimir M. Krasnov,J. Flokstra,Horst Rogalla,M. Yu. Kupriyanov +6 more
TL;DR: A microscopic model of the proximity effect in superconductor-insulator-superconductor (SS'IS"S) Josephson tunnel junctions has been developed and the current-voltage characteristics and the temperature dependence of the critical current and sum-gap voltage could be described quantitatively well.
Journal ArticleDOI
Disorder-induced transition between s± and s++ states in two-band superconductors
D.V. Efremov,Maxim M. Korshunov,Maxim M. Korshunov,Maxim M. Korshunov,Oleg V. Dolgov,Alexandre Avraamovitch Golubov,Peter Hirschfeld +6 more
TL;DR: In this paper, the authors studied disorder in two-band superconductors and showed that the suppression of Tc can be described by a single parameter depending on the intraband and interband impurity scattering rates.
