In the work, dependences of the Kerr rotation angles on magnetic field strength ((H) at the longitudinal Kerr effect in multilayer nano films [Co (0.8 nm) / Cu (111)]20 with different thickness of copper layers were analyzed with taking into account presence of superparamagnetic cobalt atoms clusters in the films. Magnetic moments of superparamagnetic particles were determined from approximation of ((H) dependencies by Langevin functions with taking into account Log-normal distributions for magnetic moments of SPM clusters. It is found that sizes of superparamagnetic clusters are reduced in the films where there are antiferromagnetic exchange bonds between layers of cobalt. It is shown that reduction of superparamagnetic cluster sizes is accompanied with increase of their total volume in cobalt layers. It is concluded that the regularities are caused by influence of electron density redistribution in the copper layers under action of the electron quantum size effect in the process of films producing. |
