Theory of fractional vortex escape in a 0-kappa long Josephson junction
K. Vogel, T. Kato, W. P. Schleich +3
We consider a fractional Josephson vortex in an infinitely long 0-kappa Josephson junction. A uniform bias current applied to the junction exerts a Lorentz force acting on a vortex…
Lower Critical Fields of Superconducting PrFeAsO Single Crystals
R. Okazaki, M. Konczykowski, C. J. van der Beek +12
We have studied the lower critical fields H_{c1} of superconducting iron oxipnictide PrFeAsO_{1-y} single crystals for H parallel and perpendicular to the ab-planes. Measurements o…
Microwave Surface-Impedance Measurements of the Magnetic Penetration Depth in Single Crystal Ba1-xKxFe2As2 Superconductors: Evidence for a Disorder-Dependent Superfluid Density
K. Hashimoto, T. Shibauchi, S. Kasahara +10
We report high-sensitivity microwave measurements of the in-plane penetration depth and quasiparticle scattering rate in several single crystals of hole-doped Fe-bas…
Microwave Penetration Depth and Quasiparticle Conductivity in PrFeAsO_1-y Single Crystals : Evidence for a Full-Gap Superconductor
K. Hashimoto, T. Shibauchi, T. Kato +9
In-plane microwave penetration depth and quaiparticle conductivity at 28 GHz are measured in underdoped single crystals of the Fe-based superconductor PrFeAsO ($T_…
Doping Dependence of Two Energy Scales in the Tunneling Spectra of Superconducting LaSrCuO
T. Kato, T. Maruyama, S. Okitsu +1
Scanning tunneling microscopy and spectroscopy have been performed on superconducting LaSrCuO (, and 0.21) at 4.2 K. Atomically resolved sur…
