josephson junctions with nb sputtered film as counterelectrode have been realized on ybco pellets. the effect of the cleaning procedure of the ybco surface in the fabrication process is discussed. the i-v characteristic at 4.2 k shows a josephson current. a rough estimation of the magnetic penetration depth is obtained by the external magnetic field dependence of the critical current
