ABSTRACTChanges in critical current properties depending on growth temperature (Ts) were clarified for Ba-Nb-O-doped YBa2Cu3Oy (Y123) films deposited by YAG- and excimer-PLD. Due to the introduction of Ba-Nb-O-nanorods, a vortex-Bose-glass-like behavior emerged as irreversibility lines and in-field critical current densities (Jcs) were improved. Crossover magnetic fields (Bcr) and in-field Jcs increased with the increase in Ts for the Y123 films with nanorods. These Ts-dependent critical current properties were attributable to the changes in morphology of the nanorods with Ts and were independent of laser source in PLD apparatuses. For the fabrication of RE123 coated conductors containing nanorods, optimization of Ts with taking both materials of RE123 matrix and nanorod into account is necessary to achieve higher in-field Jc.

Electrochemical Evaluation

Abstract Electrochemical methods have been used to compare the resistance of several stainless steel.al.loys to corrosion in chloride media. These methods consisted of the determination of critical current densities and pitting potentials, and also the amount of chloride required for passive film breakdown at a fixed passive potential. The results correlated very well with rust staining observed in exposures in a marine atmosphere. Some alloying effects were explored, and the mechanism of pitting and crevice corrosion is also discussed.
