MAGNETOSTATIC WAVES IN A THIN UNIAXIAL PLATELET WITH STRIPE DOMAINS MAGNETIZED ALONG THE EASY AXIS

The theory of magnetostatic waves propagating along the domains is introduced. It is shown that only uniform-surface and volume-uniform waves may exist. In the case k(x) --> 0 we obtain two FMR frequencies: the low-frequency mode omega(lf) as a limiting case of volume-uniform waves and the high-frequency mode omega(hf) of uniform-surface waves. Comparison with the theory of uniform resonance and experiment on barium ferrite platelets is carried out.
