Unusual persistence of superconductivity against high magnetic fields in the strongly-correlated iron-chalcogenide film FeTe:O
I. K. Dimitrov, W. D. Si, W. Ku +2
We report an unusual persistence of superconductivity against high magnetic fields in the iron chalcogenide film FeTe:O below ~ 2.5 K. Instead of saturating like a mean-field…
Iron-chalcogenide FeSeTe coated superconducting tapes for high field applications
Weidong Si, Juan Zhou, Qing Jie +7
The high upper critical field characteristic of the recently discovered iron-based superconducting chalcogenides opens the possibility of developing a new type of non-oxide high-fi…
Enhanced flux pinning in YBa2Cu3O7-d films by nano-scaled substrate surface roughness
Zuxin Ye, W. D. Si, Qiang Li +3
Nano-scaled substrate surface roughness is shown to strongly influence the critical current density Jc in YBCO films made by pulse-laser-deposition on the crystalline LaAlO3 substr…
Response of fractal penetration of magnetic flux to disorder landscape in superconducting films
Zuxin Ye, Qiang Li, W. D. Si +3
Magnetic flux front and induction contours in superconducting YBa2Cu3O7-d films with defect size s ~ l (superconducting coherence length) and s > l are studied by magneto-optical i…
Structural phase transitions in epitaxial perovskite films
Feizhou He, B. O. Wells, Z. -G. Ban +6
Three different film systems have been systematically investigated to understand the effects of strain and substrate constraint on the phase transitions of perovskite films. In SrT…
Hole Doping Dependence of the Coherence Length in Thin Films
H. H. Wen, H. P. Yang, S. L. Li +4
By measuring the field and temperature dependence of magnetization on systematically doped thin films, the critical current density and the collective…
