Description
Thin films of GdBa2Cu3O7 superconductor were grown in situ on MgO single-crystal substrates under different substrate temperatures (Ts). When Ts=800 degree C, the films were epitaxially grown with the c axis perpendicular to the film surface. The growth quality was very good, but the zero resistance critical temperature (Tc0) was only 85 K and the transition width (ΔTc) was 1.5 K. When Ts=670 degree C, some of the films were epitaxially grown with the c axis perpendicular to the film surface. Some were mainly c axis oriented with a small amount of (110) and a-axis orientation. The growth quality was relatively poor, but they had Tc0 of 89--91 K and ΔTc of 0.6--1 K
