Entropy jump at the first-order vortex phase transition in Bi2Sr2CaCu2O8+δ with columnar defects
G. Rumi, L. J. Albornoz, P. Pedrazzini +5
We study the entropy jump associated with the first-order vortex melting transition (FOT) in Bi2Sr2CaCu2O8+δ crystals by means of Hall probe magnetometry. The samples present a dil…
Disorder, critical currents, and vortex pinning energies in isovalently substituted BaFe(AsP)
Sultan Demirdis, Yanina Fasano, Shigeru Kasahara +6
We present a comprehensive overview of vortex pinning in single crystals of the isovalently substituted iron-based superconductor BaFe(AsP), a material th…
Vortex creep and critical current densities in superconducting (Ba,K)FeAs single crystals
Marcin Konczykowski, Cornelis Jacominus van der Beek, Makariy Tanatar +5
The surprisingly rapid relaxation of the sustainable current density in the critical state of single crystalline BaKFeAs is investigated for magnetic fiel…
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…
Nature of c-axis coupling in underdoped Bi2Sr2CaCu2O8 with varying degrees of disorder
Panayotis Spathis, Sylvain Colson, Feng Yang +7
The dependence of the Josephson Plasma Resonance (JPR) frequency in heavily underdoped Bi2Sr2CaCu2O8+δon temperature and controlled pointlike disorder, introduced by high-energy el…
