Abstract
Néel (or Bloch) line dynamics has been investigated in garnet epilayers characterized by huge and moderate damping parameters. Direct pressure velocities are found to be in fair agreement with expected values. Velocity saturation is, however, observed in moderately damped material. The gyrotropic coupling to wall motion is shown to produce a variety of line displacement behaviours.
