dc.description.abstractMagnetic 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-perpendicular to applied perpendicular to the film plane. With increasing B-perpendicular to the resonance mode DR(+) is confined to the small domain with equilibrium magnetization antiparallel to B-perpendicular to, while DR(-) is confined in the larger stripe having equilibrium magnetization parallel to B-perpendicular to. 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.
