An exact solution of a new superconducting state is obtained which exists for DC currents larger than the critical current in thin wires. The order‐parameter is zero at all times at certain points in the whisker, thereby permitting the phase to slip at a constant rate, a consequence of which is a de potential difference between the separate singly‐connected superconducting regions. These solutions are periodic in space and lead to voltage steps in the do voltage‐current characteristic. It is proven in the limit when the zeros of the order‐parameter are far apart that these solutions are stable.
