โฆ Synopsis
Angular dependence of the magnetoresistance and of the critical current up to 20 tesla in the bismuth 2212 phase shows remarkable anisotropic behavior. Samples are highly c-axis oriented thin films. The field dependence of the critical current is shown to be essentially dominated by the component of the magnetic field perpendicular to the CU02 layers.

Superconducting thin films of Bi-Sr-Ca-Cu-O have been deposited by KrF excimer laser ablation. The best in situ films showed a Tc o~ of 110 K and a Tcto) of 76 K. A study of the laser plume revealed the presence of two distinct regimes. The forward directed component increased with fluence and the f
