摘要:We have grown highly crystalline β -FeSe type iron chalcogenide nanowires (NWs) by annealing thin film that is prepared by a pulsed laser deposition method. Three kinds of NWs with compositions of Fe0.8Se, Fe0.88Se0.32Te0.68 and Fe...

摘要:A series of small fine-grained and single-crystal bars, with strain from 0% (recrystallized) to 50%, were given different amounts of chemical polishing. Four-point resistivity ( ρ ) data was used to characterize the electron scattering from dislocations, hydrogen, and any ot...

摘要:In this paper, we propose a slight change in the architecture of second generation (2G) high temperature superconductor (HTS) coated conductors (CCs), in order to accelerate their normal zone propagation velocity (NZPV) and reduce the probability of developing hot spots. The...

摘要:Superconductivity in compounds whose crystal structure lacks inversion symmetry are known to display intriguing properties that deviate from conventional BCS superconducting behavior. Here we report magnetization, resistivity, and heat capacity measurements on polycrystallin...

摘要:The properties of the ferromagnet/superconductor (FS) system are theoretically studied in an external magnetic field. We consider the boundary value problem for the Usadel-like equations in the case of the so-called ‘dirty’ limit. Based on a fit of theoretical and known expe...
