“…Figure 5 shows a millimeter-size image of an ultrathin stepped film in which, because of electronic quantization effects, one can observe a strong contrast from monolayer-high steps. 61 A more elaborate procedure demonstrated by Pavlov et al 62 involves a combination of high-resolution imaging with scanning the sample and a subsequent reconstruction of the total image from small parts.…”

Magnetization-induced-second-harmonic generation from surfaces and interfaces

Magnetization-induced effe_ct.s in the nonlinear optical response of magnetic media, such as magnetizationinduced-second-harmonic generation (MSHG), led to very strong and novel non linear magneto-optical effects that appear to be very sensitive to magnetic interface properties. This surface-interface sensitivity ofMSHG, in combination with the very large magneto-optical effects, has led to a fast development of this technique over the past decade. On the one hand, an extreme sensitivity of MSHG to the electronic and magnetic structure of clean surfaces has been successfully demonstrated. On the other hand, the penetration depth of light allows one to use this sensitivity to study buried interfaces in multilayer systems. Further experimental developments of the MSHG technique, such as space and time t·esolution as well as magnetization-sensitive-sumfrequency generation, appear to be promising as well.

“…Also quantum well states which occur in sandwich structures could be resolved. This has been shown both experimentally [9,[37][38][39] and theoretically [7], by exploiting the fact that NOLIMOKE spectra reflect characteristic features of the bandstructures [40]. Recent work predicted that even the influence of surface antiferromagnetism on the optical signal can be resolved by the nonlinear magnetooptical Kerr-effect (NOLIMOKE) [8].…”

“…Therefore is has attracted considerable interest in recent research on interface magnetism [2][3][4][5][6][7][8][9][10]. In this paper we investigate the dependence of the nonlinear magneto-optical Kerr-spectra and their microscopic origin [11] the spin-orbit coupling (SOC) and the magnetic moment -of Fe monolayers on structural changes.…”

Nonlinear magneto-optics of Fe monolayers from first principles: Structural dependence and spin-orbit coupling strength

1998

We calculate the nonlinear magneto-optical response of free-standing fcc (001), (110) and (111) oriented Fe monolayers. The bandstructures are determined from first principles using a full-potential LAPW method with the additional implementation of spin-orbit coupling. The variation of the spinorbit coupling strength and the nonlinear magneto-optical spectra upon layer orientation are investigated. We find characteristic differences which indicate an enhanced sensitivity of nonlinear magneto-optics to surface orientation and variation of the in-plane lattice constants. In particular the crossover from onedimensional stripe structures to twodimensional films of (111) layers exhibits a clean signature in the nonlinear Kerr-spectra and demonstrates the versatility of nonlinear magneto-optics as a tool for in situ thin-film analysis.

“…This is the reason why MSHG has been applied to studies of magnetic thin films and multilayers. [6][7][8][9][10] In most cases, isotropic MSHG from magnetic metal interfaces has been studied. The only investigated cases of anisotropic MSHG from single crystalline samples were noncentrosymmetric films of magnetic garnets 11 and antiferromagnetic crystals.…”

The anisotropic nonlinear magneto-optical response from Fe/Au͑001͒ superlattices is studied. Perfect singlecrystalline order through the whole thickness of the multilayer is observed. The magneto-optical signals are measured in both the longitudinal and transversal configurations. A strong fourfold anisotropy of nonlinear Kerr rotation angle is demonstrated, in addition to the anisotropic second harmonic intensity changes. The results are described in terms of a simple phenomenological model, that involve both dipole and quadrupole nonlinear-optical interactions. Furthermore, general, model-independent symmetry properties of the nonlinear magneto-optical response are established.
