Therefore , by assuming that the wall satisfies an equation ( 3.4 ) 4'20 / 2y = sin 0
resembling eq . ( 2.6 ) , we obtain the energy correctly to first order in H , and H ,
The spatially dependent wall parameter A ' ( x , z ) is optimized by minimizing the

metric experiments on single plane walls stabilized in an external field gradient in
a LaGa YIG film [ 46 ] . The plot of wall velocity vs. drive ( fig . 40 ) showed a linear
rise to a peak at 270 m / s compared to 550 m / s predicted from eq . ( 7.25 ) .
