9. Optical wave interactions – magnetostatic waves in integrated magneto-optics
Magnetostatic waves (MW) are magnetic disturbances that propagate at microwave frequencies in ferrimagnetic materials subjected to a magnetic field, with wavelengths between 1 μm and 1 cm . A magnetostatic wave propagating in a thin layer of ferrimagnetic garnet generates a periodic variation in the non-diagonal elements of the optical permittivity tensor. A beam propagating in integrated optics in the same garnet layer can be diffracted by this periodic polarization rotation grating.

Depending on the orientation of the applied magnetic field, there are three main modes of magnetostatic wave propagation:
