Nonlinear Thermomagnetic Waves in the Resistive State of Superconductors

The evolution of thermomagnetic perturbations in the resistive state of superconductors is considered. A qualitative pattern of the formation and further development of nonlinear stationary structures that describe the final stage of thermal and electromagnetic perturbations in a superconductor is investigated. The wave propagation velocity and the wave front width in a superconductor are estimated.
