High Critical Flux Density Gradients Near The Surface Of Superconducting Niobium
(Kluwer Academic Publishers, 1979)
Pinning of spiral fluxons by giant screw dislocations in YBA2Cu3O7-δ single crystals: Josephson analog of the fishtail effect
(MAIK Nauka/InterperiodicaMoscow, 2010-01)
By using a highly sensitive homemade AC magnetic susceptibility technique, the magnetic flux penetration has been measured in YBa2Cu3O7-δ single crystals with giant screw dislocations (having the structure of the Archimedean ...
Effect of mixed pinning landscapes produced by 6 MeV oxygen irradiation on the resulting critical current densities J c in 1.3 µm thick GdBa 2 Cu 3 O 7- d coated conductors grown by co-evaporation
(Elsevier Science, 2017-11)
We report the influence of crystalline defects introduced by 6 MeV 16 O 3+ irradiation on the critical current densities J c and flux creep rates in 1.3 µm thick GdBa 2 Cu 3 O 7- δ coated conductor produced by co-evaporation. ...
Enhancement of the critical current density by increasing the collective pinning energy in heavy ion irradiated Co-doped BaFe2As2 single crystals
(IOP Publishing, 2015-05-08)
We investigate the effect of heavy ion irradiation (1.4-GeV Pb) on the vortex matter in Ba(Fe0.92Co0.08)2As2 single crystals by SQUID magnetometry. The defects created by the irradiation are discontinuous amorphous tracks, ...
Effect of Ni doping on vortex pinning in CaK(F e1-x N ix)4 A s4 single crystals
(American Physical Society, 2019-08)
We study the correlation between chemical composition and vortex dynamics in Ni-doped CaK(Fe1-xNix)4As4 (x=0, 0.015, 0.025, 0.03, and 0.05) single crystals by performing measurements of the critical current densities Jc ...
Role of auxin during intercellular infection of Discaria trinervis by Frankia
(Frontiers in Plant Science, 2014-08)
Nitrogen-fixing nodules induced by Frankia in the actinorhizal plant Discaria trinervis result from a primitive intercellular root invasion pathway that does not involve root hair deformation and infection threads. Here, ...
Strong magnetic field dependence of critical current densities and vortex activation energies in an anisotropic clean MgB2 thin film
(Pergamon-Elsevier Science Ltd, 2015-11)
We report the influence of two-band superconductivity on the flux creep and the critical current densities of a MgB2 thin film. The small magnetic penetration depth of λ=50±10 nm at T=4 K is related to a clean π-band. We ...
Anomalous reduction in the long-time flux creep relaxation in superconducting Ca10(Pt4As8)((Fe1-xPt x )2As2)5 (x ≈ 0.05) single crystals
(IOP Publishing, 2018-05-11)
We report the vortex dynamics of superconducting a Ca10(Pt4As8)((Fe1-xPtx)2As2)5 (x ≈ 0.05) single crystal with T c = 26 K investigated by performing magnetic measurements. The field dependence of the magnetization displays ...
