Query: Stationary Thermomagnetic Waves in Superconductors   The propagation of a nonlinear stationary thermomagnetic wave in
superconducting media is qualitatively analyzed in view of the effect of an
external magnetic field. The velocity and the thickness of the wave front are
estimated. It is demonstrated that the inclusion of an external magnetic field
affects the thermomagnetic wave profile only slightly.
