Magneto-optical Properties of Spin-Valve Systems on the Basis of Au/Fe/Au/Co/Si

Abstract

This paper presents the results of investigation of magneto-optical Kerr effect in pseudo spin-valve systems on the basis of Fe, Co and Au. The significant dependence of coercetivity on such parameters as relative position of ferromagnetic layers, their thicknesses and surface morphology was shown. The investigation was carried out with AFM and TEM methods. Coercitivity value is greater for Au(3)/Fe(3)/Au(6)/Co(20)/SiO2/Si system. This is explained with different transitional metals growth mechanisms on the substrate and on non-magnetic layer and with more varied surface morphology of films with thickness about 3 nm because of three-dimensional islands in Stranski - Krastanov growth mode.
