Phase resolved measurements of spin-wave pulses. The upper panel is obtained with the conventional space- and time-resolved Brillouin light scattering setup and shows the spin-wave intensity distribution for a given time. The lower panel measured using the phase-sensitive Brillouin light scattering technique shows the corresponding phase map. The pulse duration and the carrier frequency are and , respectively. The applied field is . The white arrow indicates the direction of spin-wave propagation.
Dispersion curves of the BVMSW mode measured for two magnetizing fields. Dashed curves are obtained as a result of calculation. Insets demonstrate the wave fronts of the spin wave for the given frequencies.
Reconstruction of phase profile of a linear spin-wave pulse (left diagram) and a spin-wave envelope soliton (right diagram). The dashed lines indicate the measured envelope wave forms of the spin-wave packets. Reconstructed phase profiles are shown by the solid lines. The pulse duration and the carrier frequency are and , respectively. The applied field is .
