โฆ Synopsis
The superconducting transition of a thin, current-carrying wire at fixed temperature below T e has been studied on the basis of the Ginzburg-Landau theory. In the case of solutions uniform in space and in the case of solutions with a longitudinal structure a description of the development in time is given. Taking into account fluctuations of the complex order parameter, in the simplest case of uniformity in space we have found solutions periodic in time at overcricical currents. In this case the order parameter, the supercurrent, and the electric field are periodic in time with a well-defined frequency spectrum over a low-level noise spectrum. The electrical resistance is thereby reduced in this region.

We have measured the in-phase component of the low-frequency ac impedance of the dc current-induced intermediate state in wires of pure and impure type I superconductors. We find that this dynamic resistance of the intermediate state is greater than the normal state resistance of the wire. The linea
