✦ Synopsis

The new thermomagnetic effect in the long aosephson SNS junction (L >> ,~j) Ta/Cu/Ta has been obse.rved. This effect is caused by the thermal diffusion of eoreless aosephson vortices. The model based on the sine-Gordon equation has been proposed. From the experimental results the transport entropy has been obtained. Its value is S~ ..~ lO-X2j/Km in agreement with the theoretical estimation.
