Abstract
The influence of thermomagnetic (Ettingshausen and Nernst) effects on the stability and dynamics of the critical state in hard superconductors has been considered. Both the criteria for stability against flux jumps and the nature of a developing instability have been investigated in some simple cases. It is shown that thermomagnetic effects lead to essential changes in the dynamics of the critical state. The extent of the regime within which thermomagnetic effects lead to oscillations of the temperature and electric field during a flux jump has been investigated in terms of characteristic parameters that depend on material properties and temperature.
