Fig. 5

Snapshots of the motion of the stripe domain in the NSMM at (a) 37.5 ns, (b) 40.0 ns, and (c) 42.5 ns. d Oscillations of the magnetization and the external fields in the x1-direction. The blue curve represents the results with \(\lambda _{100}^\prime = 20.0 \times 10^{ - 5}\) and \(\lambda _{111}^\prime = - 7.22 \times 10^{ - 5}\), where \(\bar \xi _{11} = 0\), while the red curve represents the results for isotropic magnetostriction with \(\lambda _{100}^\prime = \lambda _{111}^\prime = 20.0 \times 10^{ - 5}\). The oscillating magnetic field is indicated by the dotted curve. e \(\bar \xi _{11}\) dependence of the phase differences between the external field and the domain motion. f \(\bar \xi _{11}\) dependence of the oscillation amplitudes of the domain wall motion. g \(\bar \xi _{11}\) dependence of the excess losses. In (e–g), blue and red colors represent the results for zero \(\bar \xi _{11}\) (\(\lambda _{111}^\prime = - 0.36\lambda _{100}^\prime\)) and isotropic magnetostriction (\(\lambda _{111}^\prime = \lambda _{100}^\prime\)), respectively.
