Bismuth-substituted magnetic garnet films, formulated so as to have a low magnetic quality factor Q, were grown from a bismuth-based melt using liquid-phase epitaxy. The lowest Q achieved was about 0.2. Such samples were observed to support parallel stripe domain structure and were theoretically predicted to have an "in-phase'' domain mode ferromagnetic resonance response at frequencies as low as 250 MHz. Such "in-phase'' resonances, along with the higher-frequency "out-of-phase'' mode, were observed experimentally with a variable radio frequency/fixed dc field ferromagnetic resonance spectrometer. The data, which were taken as a function of dc in-plane field, were found to be in good agreement with the theory.
