Abstract

Superconducting thin films of $BiSrCaCuO$ have been deposited using a novel electron beam evaporation technique. In this technique the crucible has a groove around its circumference and rotates continuously during deposition. The source material is loaded in the form of pellets of the composite. Both oxides as well as fluorides have been used in the starting material and a comparison of tbe film properties has been made. The best film was obtained on a $MgO$(100) substrate with a $T_c$ onset at 85 K and $T_c$ zero at 77 K using calcium fluoride in the source material.
