Abstract: | A special direction of the wave vector was found for volume magnetostatic waves (MSWs) that coincides with the cutoff angle
for surface MSWs; when crossing this direction, the field configuration for MSWs with small wavenumbers changes sharply. It
is shown that this direction corresponds to the maximum asymmetry of magnetostatic potential distribution over the film depth
and the largest wave penetration depth into the film bulk from the surface. This effect occurs also for volume MSWs propagating
in a wave channel. |
