Tuning flux-pinning in epitaxial NdBa2Cu3O7-x films via engineered, hybrid nanoscale defect structures
Sung Hun Wee, Amit Goyal, Yuri L. Zuev +1
Epitaxial NdBa2Cu3O7-x films with a hybrid nanoscale defect structure comprised of BaZrO3 nanodot arrays aligned along the c-axis in one half of the film thickness and aligned perp…
Suppression of vortex channeling in meandered YBa2Cu3O7-d grain boundaries
J. H. Durrell, D. M. Feldmann, C. Cantoni
We report on the in-plane magnetic field (H) dependence of the critical current density (Jc) in meandered and planar single grain boundaries (GBs) isolated in YBa2Cu3O7-d (YBCO) co…
Anisotropic, non-monotonic behavior of the superconducting critical current in thin YBa2Cu3O7-d films on vicinal SrTiO3 surfaces
C. Cantoni, D. T. Verebelyi, E. D. Specht +2
The critical current density of epitaxial YBCO films grown on vicinal SrTiO3 substrates was investigated by electrical transport measurements along and across the steps of the SrTi…
Self-organized current transport through low angle grain boundaries in YBaCuO thin films, studied magnetometrically
J. R. Thompson, H. J. Kim, C. Cantoni +3
The critical current density flowing across low angle grain boundaries in YBaCuO thin films has been studied magnetometrically. Films (200 nm thickness) were deposi…
RHEED Studies of Epitaxial Oxide Seed-Layer Growth on RABiTS Ni(001): The Role of Surface Structure and Chemistry
C. Cantoni, D. K. Christen, R. Feenstra +4
The epitaxial deposition of the first oxide buffer layer (seed layer) on biaxially textured Ni tape for coated conductors is a critical step that is dependent on the atomistic surf…
