Anisotropic dynamical scaling near the vortex-glass transition of twinned YBa sub 2 Cu sub 3 O sub 7- delta

Anisotropic dynamical scaling near the vortex-glass transition of twinned YBa sub 2 Cu sub 3 O sub 7- delta

The complex electrical conductivity sigma ( omega ) is determined from the linear ac susceptibility at 3 Hz-3 MHz in fields of 0.4-12 T parallel and perpendicular to the c-axis in a twinned crystal. Dynamical scaling of single bond sigma single bond and sigma prime prime / sigma prime reveals orderi...

Zusammenfassung:The complex electrical conductivity sigma ( omega ) is determined from the linear ac susceptibility at 3 Hz-3 MHz in fields of 0.4-12 T parallel and perpendicular to the c-axis in a twinned crystal. Dynamical scaling of single bond sigma single bond and sigma prime prime / sigma prime reveals ordering temps. and field-independent scaling functions. Results are discussed.
