Ferromagnetic domain walls are observed to move from the hot to the cold end of samples of amorphous (Co92.5Fe7.5)78Mo2B15Si5subjected to a constant temperature gradientdT/dx. An ac magnetic fieldH0Eparallel to the easy axis is used to decrease pinning forces on the walls. The critical temperature gradient (dT/dx)crequired to move walls is of order 102K/mm. The linear decrease of (dT/dx)cwith increasingH0Eindicates that pinning of the walls by the two ends of the sample is dominant over bulk pinning. The dependence of (dT/dx)con sample length and thickness indicates that the Nernst–Ettingshausen drive mechanism is dominant over competing drive mechanisms. The speed of walls has been measured and is found to increase with increasing temperature gradient.
