Abstract

We report the growth of (Cu C)Ba2Ca(n-1)Cun Oy (n=1-4) superconducting thin films by the molecular beam epitaxy method. The film was c-axis oriented for n=1, and was changed to a-axis oriented with 90° domains for n=2-4. All the films exhibited superconductivity and their Tc's were Tc(on)=35 K and Tc(zero)=18 K for n=1, Tc(on)=80 K and Tc(zero)=52 K for n=2, Tc(on)=85 K and Tc(zero)=42 K for n=3, and Tc(on)=105 K and Tc(zero)=53 K for n=4.
