Enhanced critical-current in P-doped BaFe2As2 thin films on metal substrates arising from poorly aligned grain boundaries
Thin films of the iron-based superconductor BaFe2(As1-xPx)2 (Ba122:P) were fabricated on polycrystalline metal-tape substrates with two kinds of in-plane grain boundary alignments (well aligned (4°) and poorly aligned (8°)) by pulsed laser deposition. The poorly aligned substrate is not applicable to cuprate-coated conductors because the in-plane alignment >4° results in exponential decay of th...
متن کاملEPITAXIAL YBa 2 Cu 307 ON BIAXIALLY TEXTURED ( 001 ) NI : AN APPROACH TO HIGH CRITICAL CURRENT DENSITY SUPERCONDUCTING TAPES
In-plane aligned, c-axis oriented YBazCu307 (YBCO) films with superconducting critical current densities, Jc, as high as 700,000 amperes per square centimeter at 77 kelvin have been grown on thermo-mechanically, rolled-textured (00 1) Ni tapes using pulsed-laser deposition. Epitaxial growth of oxide buffer layers directly on biaxially textured Ni, formed by recrystallization of cold-rolled pure...
متن کاملBiaxially oriented CaF2 films on amorphous substrates
Biaxially oriented CaF2 films have been created by first using an oblique incidence vapor flux to deposit CaF2 onto an amorphous surface to form vertically aligned nanorods which served as seeds to grow a more continuous CaF2 capping layer under a subsequent normal incidence flux deposition. The entire film possesses a unique {111}/121S biaxial texture as shown by X-ray pole figure analysis and...

متن کاملCharacterization of highly-oriented ferroelectric PbxBa1−x TiO3 thin films grown by metalorganic chemical vapor deposition
PbxBa1−xTiO3 (0.2 x 1) thin films were deposited on single-crystal MgO as well as amorphous Si3N4/Si substrates using biaxially textured MgO buffer templates, grown by ion beam-assisted deposition (IBAD). The ferroelectric films were stoichiometric and highly oriented, with only (001) and (100) orientations evident in x-ray diffraction (XRD) scans. Films on biaxially textured templates had smal...
