“…SHG and all even‐order NLO effects can be highly sensitive to the symmetry breaking from the crystalline lattice, to geometric field‐enhancements, as well as to the presence of electric and magnetic order. Consequently, SHG can serve to probe ferroelectric and ferromagnetic domains.…”

Recent advances in nonlinear optics, hot electrons for renewable energy (e.g., solar cells and water‐splitting), acousto‐optics, nanometalworking, nanorobotics, steam generation, and photothermal cancer therapy are reviewed here. In all these areas, one of the key enabling properties is the ability of metallic nanoparticles to harvest and control light at the subwavelength scale by supporting coherent electronic oscillations, called localized surface plasmon resonances (LSPRs). Various physical properties and potential areas of application emerge depending on the decay mechanism of the LSPR and, especially, depending on the considered timescale. The field of plasmonics has mainly been associated with manipulating electromagnetic near‐fields at the nanoscale, where absorption is an obstacle. However, plasmonic absorption leads to a stream of temperature‐related phenomena that have only recently attracted significant attention. The goal of this review is to highlight exciting new areas of research (such as nanorobotics, nanometalworking, or acousto‐optical techniques) and to survey the most recent progress in more established areas (such as hot electrons, photothermal therapy, and plasmonic steam generation). To set each research area in context, the text is organized around the thermal cycle of the nanoparticles.

“…The SHG process is also highly sensitive to externally applied electric [10] or magnetic [11,12] dc fields; though care should be taken while estimating the latter [13]. When combined with microscopy, SHG can successfully image ferroelectric [14] and ferromagnetic [15] domains, as well as local field enhancements [16][17][18].…”

Abstract:While it has been demonstrated that, above its resolution limit, Second Harmonic Generation (SHG) microscopy can map chiral local field enhancements, below that limit, structural defects were found to play a major role. Here we show that, even below the resolution limit, the contributions from chiral local field enhancements to the SHG signal can dominate over those by structural defects. We report highly homogeneous SHG micrographs of star-shaped gold nanostructures, where the SHG circular dichroism effect is clearly visible from virtually every single nanostructure. Most likely, size and geometry determine the dominant contributions to the SHG signal in nanostructured systems. References and links1. J. B.

“…Since the theoretical predictions in the 1980's [20][21][22][23] and subsequent first experimental observations [24][25][26][27] the method has been widely used and proved to be a highly sensitive tool to investigate surface and interfacial magnetic properties of thin films and multilayers. [28][29][30][31][32] The first theoretical activities 22,23 were devoted to the treatment of MSHG ͑or nonlinear Kerr effect͒ from infinitely thin magnetic layers, where the electro-dipole SHG appears due to the breaking of the inversion symmetry at the surface or interface. The phenomenological model describing MSHG in magnetic multilayers formed by sequence of magnetic and nonmagnetic centrosymmetric thin films was elaborated in Refs.…”

Interfacial magnetization in exchange-coupledFe∕Cr∕Festructures investigated by second harmonic generation

We have studied the magnetic field dependences of magnetic optical second harmonic generation ͑SHG͒ in MBE-grown Fe/ Cr/ Fe/ Ag/ GaAs͑100͒ heterostructures displaying both bilinear and biquadratic interlayer exchange coupling. The magnetic field H was applied in the ͑100͒ surface plane along both easy ͓͑001͔͒ and hard ͓͑110͔͒ axes of the in-plane fourfold magnetic anisotropy. The SHG has been measured in reflection at near normal incidence for different polarization combinations ͑pp , ps , ss , sp͒ of the fundamental and second harmonic light in longitudinal and transversal geometries. The magnetic field variation of the SHG signal clearly reflects the field-induced transformations of the magnetic state at the interfaces in the trilayer. It strongly depends on the configuration of light polarization, experimental geometry ͑longitudinal or transversal͒, and orientation of the magnetic field H relative to the crystal axes. In contrast to linear magneto-optical Kerr effect, which is odd in magnetic field, magnetic SHG is either even in H or does not display a definite parity at all, depending on the polarization configuration. We interpret the data based on a model accounting for nonmagnetic and magnetic contributions to SHG from the surface and interfaces described by C 4v point symmetry. Taking into account the changes of the mutual orientation of interfacial magnetizations allows us to describe the general features of the measured field dependences of SHG.
