Abstract
We have investigated subgap characteristics of Nb/AlOx/Nb tunnel junctions with high critical current density (high-J/sub c/). A good agreement of the experimental data with the solution of Werthamer's equation clearly shows that steep current steps observed at odd submultiples of the gap voltage, which cannot be explained by multiparticle tunneling and/or multiple Andreev reflection, are mainly caused by Josephson self-coupling. Our experimental results suggest that Josephson self-coupling is important to high-J/sub c/ tunnel junctions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
