Web1 aug. 1990 · Superconducting thin films of HoBa 2 Cu 3 O 7−α have been prepared by magnetron sputtering technique. The x-ray diffraction indicated that the 1-2-3 film is composed of well-oriented grains with c-axes normal to the ZrO 2 (Y) substrate. We have studied the temperature and field dependence of critical currents density of these films.
