“…This implies a correlation between the steady-state and dynamic Kerr effects. Note that a correlation between the magnetic transport and nonlinear optical properties in granular nanocomposites was earlier observed experimentally in [3]. Revealing the mechanisms responsible for the interrelation of these phenomena appears to be an interesting task for further studies.…”

“…This interest can be attributed primarily to the giant magnetoresistance (GMR) effect observed in these materials [1]. In addition, nanocomposites exhibit a number of other unusual magnetic, electrical, optical, and magnetooptical properties, among which one can place the possibility of varying the electrical resistivity within a broad range, enhancement of optical nonlinearities [2], a correlation between the magnetic transport and nonlinear optical properties [3], the high magnetorefractive effect [4], and high electromagnetic-radiation absorption in the rf and microwave regions [5]. Although some physical mechanisms responsible for these phenomena still remain unclear, granular nanocomposites can be confidently classed among materials promising for use in developing reading heads and magnetooptical storage components [6,7].…”

-Granular silicon oxide films with embedded CoNbTa ferromagnetic particles and different relative contents of the metal and dielectric phases were studied using both steady-state and dynamic magnetooptical techniques with subpicosecond time resolution. Measurements were conducted in the spectral interval from 1.45 to 1.70 eV. The concentration dependences of the linear and photoinduced Kerr effects were found to behave similarly. Both relations are nonmonotonic with a maximum lying near the percolation threshold.

“…93 B. Magnetization-Induced Sum-Frequency Generation from Surface Plasmons In fact SHG is just a degenerate case of the general nonlinear optical process of three-wave mixing w 1 + w 2 = w 3 • The argument of symmetry breaking at interfaces, which yields the interface specificity of MSHG, should apply equally to magnetization-induced-sumfrequency generation (MSFG). Although SFG has been used for surface studies for more than a decade, 94 -96 nothing is known of the magnetic properties of SFG.…”

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.

“…Nonlinear-optical studies were performed for the composite structures made by all three composition methods using the second harmonic generation (SHG) spectroscopy technique [12]. In this experiment the fundamental wavelength of a Ti-sapphire laser with the 80 fs pulse duration tunable in the wavelength range 720-890 nm was used as the fundamental radiation, that was focused on the sample into a spot of approximately 36 μm in diameter.…”

Here we demonstrate the composition of a 3D porous quartz matrix infiltrated by silver nanoparticles as a possible application for surface enhanced Raman scattering (SERS) investigations. Various types of infiltration techniques applied for the incorporation of plasmonic Ag nanoparticles inside the pores are considered. We observe an enhancement of the second harmonic generation intensity, two-photon luminescence and nonlinear absorption in the composite metal-dielectric structures in the spectral vicinity of the localized surface plasmon resonance in silver nanoparticles, which confirms the related amplification of the local field effects in these 3D composite structures.
