抄録

We have investigated the superconducting properties and surface morphologies of c-axis-oriented SmBCO thick films on MgO substrate deposited by pulsed laser deposition. The critical current values in the SmBCO films deposited using the x=0.04 and x=0.08 (Sm-rich) targets increased with increasing film thickness, whereas their values in the films using x=0 targets were held constant. From the AFM images, the terrace widths of the Sm-rich thick films are wider than the widths of the stoichiometric films. Therefore the surface roughness arising from the increasing film thickness is improved using the Sm-rich film.
