Abstract
Using the newly developed phase-sensitive Brillouin light scattering spectroscopy technique we investigate the nonlinear influence of the spin-wave amplitude on the spin-wave phase. Nonlinear phase splitting between the peak and the tail of nonlinear spin-wave pulses was observed for dipolar-dominated spin-wave pulses propagating in yttrium-iron-garnet spin-wave waveguides. A model to describe this effect is presented. Copyright (c) EPLA, 2007.
