Effect of heavy-ion irradiation on London penetration depth in over-doped Ba(Fe,Co)2As2
J. Murphy, M. A. Tanatar, Hyunsoo Kim +7
Irradiation with 1.4 GeV Pb ions was used to induce artificial disorder in single crystals of iron-arsenide superconductor Ba(FeCo)As and to study its e…
Infrared Vortex-State Electrodynamics in Type-II Superconducting Thin Films
Xiaoxiang Xi, J. -H. Park, D. Graf +2
The vortex-state electrodynamics of s-wave superconductors has been studied by infrared spectroscopy. Far-infrared transmission and reflection spectra of superconducting NbTiN and…
Direct measurement of the upper critical field in a cuprate superconductor
G. Grissonnanche, O. Cyr-Choiniere, F. Laliberte +20
The upper critical field Hc2 is a fundamental measure of the pairing strength, yet there is no agreement on its magnitude and doping dependence in cuprate superconductors. We have…
Angular-dependent upper critical field of overdoped Ba(FeNi)As
J. Murphy, M. A. Tanatar, D. Graf +5
In-plane resistivity measurements as a function of temperature, magnetic field and its orientation with respect to the crystallographic plane were used to study the upper crit…
Physical properties of KxNi2-ySe2 single crystals
Hechang Lei, Kefeng Wang, Hyejin Ryu +3
We have synthesized K0.95(1)Ni1.86(2)Se2 single crystals. The single crystals contain K and Ni deficiencies not observed in KNi2Se2 polycrystals. Unlike KNi2Se2 polycrystals, the s…
