Stability mechanisms of high current transport in iron-chalcogenides superconducting films
Antonio Leo, Gaia Grimaldi, Pasquale Marra +8
The improvement in the fabrication techniques of iron-based superconductors have made these materials real competitors of high temperature superconductors and MgB. In particula…
Competition between intrinsic and extrinsic effects in the quenching of the superconducting state in FeSeTe thin films
Antonio Leo, Pasquale Marra, Gaia Grimaldi +6
We report the first experimental observation of the quenching of the superconducting state in current-voltage characteristics of an iron-based superconductor, namely, in FeSeTe thi…
Two-band conductivity of a FeSeTe film by reflectance measurements in the terahertz and infrared range
A. Perucchi, B. Joseph, S. Caramazza +7
We report an infrared spectroscopy study of a 200 nm thick FeSeTe film grown on LaAlO with T=13.7 K. We analyze the 20 K normal state absolute reflectance R…
High temperature heat treatment of B precursor and P.I.T. process optimization to increase Jc performances of MgB2-based conductor
Maurizio Vignolo, Gianmarco Bovone, Cristina Bernini +4
Promising results reported in our previous works led us to think that production of B powder plays a crucial role in MgB2 synthesis. A new method for boron preparation has been dev…
Highly effective and isotropic pinning in epitaxial Fe(Se,Te) thin films grown on CaF2 substrates
V. Braccini, S. Kawale, E. Reich +8
We report on the isotropic pinning obtained in epitaxial Fe(Se,Te) thin films grown on CaF2 (001) substrate. High critical current density values larger than 1 MA/cm2 in self field…
