Grain boundary microstructure and transport critical current density in YBa{sub 2}Cu{sub 3}O{sub x} [electronic resource]
It is proposed that the transport critical current (J{sub c}) density for high-{Tc} thin films, bicrystals, and bulk ceramics is determined by magnetic field penetration into the grain boundaries; the grain orientation may not in all cases be an important factor. The parameter (λ{sub L}/λ{sub J})² c...

| Summary: | It is proposed that the transport critical current (J{sub c}) density for high-{Tc} thin films, bicrystals, and bulk ceramics is determined by magnetic field penetration into the grain boundaries; the grain orientation may not in all cases be an important factor. The parameter (λ{sub L}/λ{sub J})² can characterize the strength of the grain boundary coupling, which depends mainly on the crystal coherence and the structure of the boundary. |
