Magnetic garnet films of composition (Y, Bi)3(Fe, Al)5O12 are grown by liquid phase epitaxy on [111] oriented substrates of Gd3Ga5O12. They support periodic lattices of parallel stripe domains. A planar slot line antenna is used to excite the domain wall resonance and the two branches of the domain resonance in the frequency range up to 4 GHz. Linearly polarized light passes the crystal perpendicular to the film plane and is diffracted and modulated by the excited domain lattice. The modulation intensity is measured at zero diffraction order as function of frequency and of the static induction applied in the film plane parallel to the stripes. The experimental results are in agreement with calculations on the basis of a hybridization model which takes into account the interaction of all resonances. From the experimental data the precession angles and the wall oscillation amplitudes are derived.

Magnetic garnet films of composition Y3–xBixFe5–yAlyO12 are grown by liquid phase epitaxy on [111] and [110] oriented substrates of gadolinium gallium garnet. They have high uniaxial anisotropy and support lattices of parallel stripe domains. The two branches DR+ and DR− of the domain resonance are excited by rf magnetic fields polarized in the film plane. Resonance frequencies of more than 7 GHz are observed; they are measured as function of a static induction B⟂ applied perpendicular to the film plane. With increasing B⟂ the resonance mode DR+ is confined to the small domain with equilibrium magnetization antiparallel to B⟂, while DR− is confined in the larger stripe having equilibrium magnetization parallel to B⟂. At the collapse induction the DR− mode merges into the ferrimagnetic resonance. The resonance modes DR± are calculated using a new method to determine the demagnetizing energy. Excellent agreement between theory and experiment is obtained.
