We deposited Bi2Sr2Can-1CunOy (Bi-based) superconducting thin films by the RF magnetron sputtering under external magnetic field of about 1 T. The as-deposited films were Bi-2223 single-phase, and their Tc was about 70 K without any in-situ or ex-situ annealing process. Therefore, this method is thought to be useful for obtaining the Bi-based films with high Tc.
