Аннотация:Multilayer nano-granular film structures (CoFeB)m(SiO2)100-m have been investigated by ferromagnetic resonans (FMR).It is shown experimentally that for these films which magnetic phase content is below percolation threshold the variation of FMR fields is not relatod to the thickness of magnetic layers but can be explained by variation of the shape(elongation) of spheroidal magnetic granules.The observed result are explained within standard phenomenological FMR theory.
