✦ Synopsis

The thermoelectric mechanism of the asymmetrical velocity of normal zone propagation in superconductors, relative to the direction of the transport current is suggested. The difference of the normal-superconducting interface velocities parallel and anti-parallel to the current direction due to this mechanism is of the order of 1 -50 cm s 1 for different metals. The thermoelectric effect (Thomson heat) has a hysteresis which occurs opon destruction (or restoration) of superconductivity in the sample with respect to the transport current.
