Image characterization was done in scanning/transmission mode employing a bright-field detector. Phase identification was confirmed using Selected Area Electron Diffraction (SAED). The discontinuous multilayer systems [Fe(dFe)/SiO2(3)]n/Sub, where n = 10 is the number of bilayer repeaters, were prepared by sequential magnetron sputtering on the copper mush with a carbon layer. The deposited films were annealed at different temperatures (200 and 400 С) in an Ar+N2(2%) environment using an annealing furnace with a continuous gas flow.Pylypenko, O., Pazukha, I., Shkurdoda, Y. et al.
