Stationary thermomagnetic waves in superconductors

The qualitative picture of the nonlinear stationary thermomagnetic wave extension in a superconductor with an account of the external magnetic field effort on the critical current density is studied. The motion velocity and the wave front width are evaluated. It is shown, that the account for the external magnetic field effect almost does not change the profile of the nonlinear thermomagnetic wave. The above qualitative analysis may be suitable for experimental study on the dynamics of the magnetic flux penetration into the superconductor, located in the external magnetic field, and by developing the constructive measures for protection of superconducting devices
