Popis: Experimental and theoretical research on magnetoelastic properties of nanoscale magnetic multilayers is reviewed. It has been suggested that localization of magnetoelastic strains at the interface leads to the dependence of effective magnetostriction constants on the thickness of magnetic sublayers. Various experimental techniques can be used to measure magnetoelastic tensor components. It is shown that the most effective method to study magnetostriction of magnetic nanoscale films and multilayers is strain modulated ferromagnetic resonance. It is argued that this method can be used to separate the intrinsic surface effects from the interdiffusion induced effects. The origin of the surface magnetoelastic coupling is analyzed and qualitatively attributed to many different mechanisms. It is shown that the state of the interface in magnetic multilayers is an important parameter to which the magnetostriction seems to be sensitive.
