Caracterização de fitas supercondutoras 2G HTS em regime de Flux flow
… Superconductor (2G HTS) tapes beyond the Flux Creep regime. Since the value of N is extremely sensitive to the HTS tape temperature, the attention was held for ways to minimize the tape temperature oscillation during V-I measurements. First, a special copper sample holder was designed for …

Electrical and magnetic properties of twin-free single-crystal praseodymium-doped YBa2Cu3O7-d
… the Anderson-Kim model ofthermally activated flux-creep, we calculated the effective flux pinning energy, U, for each sample. The results show that for Tffc < 0.45, U exhibits a weak dependence on Pr concentration, whereas for T/Tc > 0.45, U shows a clear maximum at x = 0.2. In addition, we …

The two-dimensional vibrating reed technique: a study of anisotropic pinning in high-temperature superconductors
… superconductor leads to the distortion of the flux lines and displacement of the vortices from the point-like oxygen defects, which act as pinning centers. The pinning force leads to additional restoring force which causes a typical magnetic field dependence of the resonance frequency. Such an …
