“…The domain wall mobilities of the initial and ordinary slope can be estimated approximately using their analysis of the 7-1 against H2 relation (about 25 cm s-1 Oe-1 for the initial slope and about 2000 cm s-1 Oe-1 for the ordinary slope). The latter high value of mobility agrees within an order of magnitude with results that had been obtained from the same material by Ross01 (1969) and by Capeland and Spiwak (1971).…”

“…Rossol (1969) has also reported a low mobility value of about 25 cm s-1 Oe-1 at 130 K. It is interesting to note that the present mobility values, as derived from the initial slope measured at room temperature, indicate the same order of magnitude as their results which were obtained at the lower temperature. Recently Capeland and Spiwak (1971) have reported a nonlinear relation of YFe03 mobility at room temperature. They defined 'dynamic coercivity' (in their paper this is called Ho) in the same way as our present Ht definition, but their value was 1 Oe or less, which is different from the Ht value of the present experiments by an order of magnitude.…”

The mobilities of the magnetic domain wall in yttrium orthoferrite, YFeO3, as grown by the flux method were investigated by the bubble collapse method. The observed relationship between the domain wall velocity and the drive pulse field was nonlinear, having the following features: (i) an initial low-mobility slope (similar 25 cm s−1 Oe−1); (ii) a transition region; and (iii) an ordinary high-mobility slope (similar 2000 cm s−1 Oe−1). The initial low mobility at low drive field was increased about 2 times after x-ray irradiation. The ordinary high mobility at high drive field was slightly increased after irradiation.The difference in the improvement of mobility at the initial and ordinary slope after x-ray irradiation suggests that the damping mechanism of domain wall motion is not the same for these two regions.
