The structure of CeO2 films grown on (1102) sapphire and on YBCO thin films was investigated. The films reported on here were grown by pulsed excimer laser deposition and their surface structure was probed using atomic force microscopy. We found that CeO2 films grown on sapphire were epitaxial with a granular structure which is smooth on an atomic scale. We see evidence of a surface reconstruct...

Lanthanum zirconate (LZO) films from water-based precursors were deposited on Ni-5%W tape by chemical solution deposition. The buffer capacity of these layers includes the prevention of Ni oxidation of the substrate and Ni penetration towards the YBCO film which is detrimental for the superconducting properties. X-ray Photoelectron Spectroscopy depth profiling was used to study the barrier effi...

In this study, High temperature superconductor YBa2Cu3O7-x (YBCO) nanoparticle was prepared by Sol-gel technique. The sol-gel includes a homogeneous solution of Y-Ba-Cu acetate precursor and acetic acid. powder compressed hydraulic at 5 ton/cm2 needed post-reaction heat treatment 850 °C for 8 h with oxygen flow. YBCO bulk has been characterized using traditional R-T measurements, producing best...

We report a successful fabrication of long-length RABiTS-based coated conductors (CC) via chemical solution deposition starting from colloidal YBa2Cu3O7-δ (YBCO) solutions containing 5 mol-% preformed BaMO3 (M = Hf, Zr) nanocrystals. Partial optimization the existing continuous reel-to-reel YBCO processing design experiments (DoE) approach allowed us to obtain nanocomposites that retain 80-90% ...

as a new precursor, [tris(2-hydroxyacetophenato) triaqua(iii)], [y(hap)3(h2o)3]; complex was used in thermal decomposition process for the synthesis of rod-like high-temperature ceramic ybco with length of about 320-350 nm and diameters 60–90 nm. the as-synthesized products were characterized by xrd, ft-ir, tem, sem and edx analyses. the results showed that by using fine raw materials, the calc...

It has been predicted that the zero frequency density of states of YBCO in the superconducting phase can display interesting anisotropy effects when a magnetic field is applied parallel to the copper-oxide planes, due to the diamagnetic response of the quasi-particles. In this paper we incorporate paramagnetism into the theory and show that it lessens the anisotropy and can even eliminate it al...
