Abstract

We report the growth of (Cu,C)Ba2Ca(n-1)CunOy (n = 2, 4) thin films on NdGaO3(1 0 0) and LaSrGaO4(0 0 1) substrates by molecular-beam epitaxy (MBE). For n = 2, we synthesize superconducting films with Tc(on) ∼85 K and Tc(zero) ∼50 K on NdGaO3. The film is a-axis oriented with 90° domains, and the lattice parameters are a = 3.894 Å and c = 11.634 Å. We also obtained a-axis oriented superconducting films for n = 4 with Tc(on) ∼105 K and Tc(zero) ∼53 K.
