Abstrakt: For nanodimensional magnetically inhomogeneous amorphous granular films of the system (Co84Nb14Ta2) x (SiO2)100− x , 30≤ x≤60 at.% the concentration dependences of the magnetooptical Kerr effect (MOKE) spectra and FMR have been investigated. The observed changes in the MOKE and FMR spectra are associated with transformations of microstructure and topology of the nanocomposites. For the compositions within the percolation region the transversal Kerr effect increases by an order of magnitude. [ABSTRACT FROM AUTHOR]
