A model incorporating the thermodynamic equilibrium oxygen content, oxygen in-diffusion, and oxide phases for the oxygenation of the YBa2Cu3O7−x is described. For sintered polycrystals, grain growth and the resulting grain size distribution are inc

Magnetic shields for SQUID applications were successfully fabricated using high Tc superconducting Bi–Sr–Ca–Cu–O (BSCCO). In order to produce shields with adequate superconducting properties and close dimensional control, it was necessary to

Nanostructured NixCo100−x films were deposited on Cu substrates by reducing the constituent metal salts in refluxing ethylene glycol at 194 °C. The average crystallite size increased with x, and reached a maximum of 64 nm when x=100. The coercivit

A Sm-poor mixture of Fe-substituted Sm2Co17, having the nominal stoichiometry of Sm0.080Co0.645Fe0.276, was ball-milled to explore the possibility of enhancing its remanence through direct microstructural refinement. With milling, the Sm2(Co0.7Fe0.3)

We have studied the properties of a series of spinel ferrite thin films prepared from aqueous solutions at temperatures slightly below 100/spl deg/C, for a range of compositions from pure Fe/sub 3/O/sub 4/ to about Ni/sub 0.34/Zn/sub 0.18/Fe/sub 2.48

The new BiSrCaCuO high T c superconductor has been processed by coprecipitation from aqueous nitrate solutions. This technique results in nearly atomic scale mixing of the starting constitutions and a more reactive starting powder than co
