摘要：

We demonstrate contiguous Shapiro steps of orders 0 and 1 having amplitudes of 1 mA in a YBa2Cu3O7-delta step-edge junction operated at 38 K, A wide-junction model that includes self-field effects explains why the observed step amplitudes are smaller than expected from the resistively shunted point-junction model. In spite of their reduced amplitudes, the observed steps are suitable for use in a proposed rapidly programmable Josephson voltage standard.
