Magnetooptical Kerr effect in the near field of a nanowire supporting surface plasmons

摘要: In terms of Green’s functions, a theory is developed describing the resonant magnetooptical Kerr effect in light scattering by linear probe that parallel to surface magnet and placed at subwavelength distance from it. The supposed be metal nanowire supporting long-lived plasmons forming near field “probe + image” complex. interaction between sample taken into account within self-consistent approximation multiple-scattering theory, included magnetization. problem scanning near-field microscopy with solved analytically case where magnetization both plane incidence (longitudinal effect). polarization, spectral, angular characteristics scattered modulated are discussed. It shown modulation intensity significantly enhanced when resonantly excited nanowire.
