In-depth selectivity of the magnetic second-harmonic generation of light in a multilayer structure

Abstract

The in-depth selectivity of magneto-optical second-harmonic generation (MSHG) is investigated in the CoO/Co/NiO/Fe-Ni/Cu film structure. The p inpout MSHG is essentially selective to only one NiO/Fe-Ni buried magnetic interface, whereas PinSout and S inPout MSHG is shown to be magnetically sensitive to all interfaces. MSHG data are also compared to the usual longitudinal Kerr effect. Symmetry arguments and calculations point out that the observed in-depth MSHG selectivity is mainly linked to the electric field profile of the incident radiation through the multilayer structure.
