โฆ Synopsis
The anisotropy of the ab-plane optical conductivity and de resistivity of single-domain BizSrzCaCuzOs crystals has been measured between 20 and 300 K. There is a modest normal-state anisotropy, optical anisotropy below T~, and an unexpected anisotropy in the resistive transition.

Susceptibility, resistivity and X-ray diffraction measurements have been performed on single crystals of BiESr2CaCu208+ 8. Very sharp (0.5 K width) superconducting transition temperatures as low as 55 K have been reached in the overdoped part of the phase diagram. Anneals in low oxygen pressures hav
