Abstract :
The domain-wall mobility has been measured in (Gd1-x Tbx )3 Fe5 O12 and (Gd1-x Dyx )3 Fe5 O12 for 
in the range 0 to 0.33. All the measurements were performed at 25°C on flux-grown crystals, and the mobility was found to vary from 2250 (cm/s)/Oe for Gd3 Fe5 O12 to 160 (cm/s)/Oe for (Gd0.67 Dy0.33 )3 Fe5 O12 and 78 (cm/s)/Oe for (Gd0.67 Tb0.33 )3 Fe5 O12 . The damping of the wall motion was found to increase linearly with to a good approximation. A method of determining the wall mobility in bulk samples from measurements of the RF susceptibility spectra is described. The results are discussed in terms of the slow relaxation model.
