The magnetically induced second harmonic generation (MSHG) technique was used to study surface magnetism in Fe/Au and Co/Ru superlattices. A mode-locked Ti-sapphire laser was used as a laser source emitting laser beams at an incident angle of 45°. The sample was mounted on a computer-controlled rotating stage to obtain the azimuthal angle-dependence of the MSHG signal. The X-ray diffraction and electron diffraction analyses elucidated that the Fe/Au superlattices followed the symmetry of MgO(001) substrate.
