Abstract

We report the deposition of NdBa2Cu3O7-δ (NBCO) thin films with a large diameter of over 5 in. by molecular-beam epitaxy (MBE). We examined the uniformity of the film composition and Tc for areas with a diameter of 140 mm. The film composition was Ba/Nd:Cu/Nd = 1.79 ± 0.02:2.97 ± 0.04, which indicates a uniform deposition over a large area. The Tc values only varied from 90.4 K to 91.6 K, which also confirms the uniform deposition. Thus our deposition method appears to be promising for producing thin film on a commercial scale.
