Anisotropic phase diagram and strong coupling effects in Ba1-xKxFe2As2
U. Welp, R. Xie, A. E. Koshelev +5
We present a thermodynamic study of the phase diagram of single-crystal Ba1-xKxFe2As2 using specific heat measurements. In zero-magnetic field a clear step in the heat capacity of…
Caloric Determination of the Upper Critical Fields and Anisotropy of NdFeAsO1-xFx Single Crystals
U. Welp, R. Xie, A. E. Koshelev +4
We present heat capacity measurements of the upper critical fields of single-crystal NdFeAsO1-xFx. In zero-magnetic field a clear step in the heat capacity is observed at Tc = 47K…
Composite to tilted vortex lattice transition in in oblique fields
Marcin Konczykowski, Cornelis Jacominus Van Der Beek, Alexei E. Koshelev +3
Precision measurements of the vortex phase diagram in single crystals of the layered superconductor BiSrCaCuO in oblique magnetic fields confirm the exist…
Microscopic theory of thermal phase slips in clean narrow superconducting wires
A. Zharov, A. Lopatin, A. E. Koshelev +1
We consider structure of a thermal phase-slip center for a simple microscopic model of a clean one-dimensional superconductors in which superconductivity occurs only within one con…
Slowing down Josephson vortex lattice in Bi_2Sr_2CaCu_2O_{8+d} with pancake vortices
A. E. Koshelev, Yu. I. Latyshev, M. Konczykowski
We study theoretically and experimentally influence of pancake vortices on motion of the Josephson vortex lattice in layered high-temperature superconductors. Mobility of the Josep…
Radiation From Flux Flow In Josephson Junction Structures
L. N. Bulaevskii, A. E. Koshelev
We derive the radiation power from a single Josephson junction (JJ) and from layered superconductors in the flux-flow regime. For the JJ case we formulate the boundary conditions f…
