Abstract
AbstractSome calculations exist for the mobility and the effective mass of ferromagnetic domain walls of special wall structures. More generally valid derivations and formulas are presented here, which are not restricted to a special wall structure. It is shown that the nonlinearity observed by several authors in the dependence of the wall velocity on the field can be predicted theoretically if the material inhomogeneities causing the coercivity are taken into account in an appropriate manner. For a special example the existence of the wall contraction and the velocity limit shown by Enz for a wall without damping and without field is shown for a wall with damping and with field. As is the approximation by Enz, the present approximation also is not able to indicate the value of this velocity limit.
