Abstract

Magnetic second harmonic generation (MSHG) signals from the Fe/Au superlattices grown on MgO (100) substrate have been investigated. The measurements were carried out in the longitudinal Kerr geometry with a 45° incidence. The magnetic field of ±0.2 T was applied to provide a magnetic saturation. The polar plot of azimuth dependence of the MSHG intensity showed a four-fold symmetry pattern similar to that observed in Fe/Au superlattices modulated by integer atomic layers. Azimuthal patterns show 45° rotation by reversing the magnetic field. Nonlinear Kerr rotation angle of 23.2° was observed in the x = 3.75 superlattice.
