Abstract

In this article the magneto-optics of magneto-optical (M-O) layered structures have been studied theoretically and experimentally. For the air/M-O/air configuration, an analytic expression between the apparentcomplex Faraday rotation and the eigenvalue <(phi)over tilde (F)> = e(1)<(phi)over tilde' (F)> can be obtained, when the M-O layers are semitransparent and weakly magnetic. The interference factor e(1) is a function of the optical constants and the M-O layer thickness d, and thelight wavelength. In these structures, the apparent Faraday rotation consists of two parts. One oscillates as a function of the M-O layer thickness and the other is proportional to the layer thickness. The oscillation period and the amplitude are determined by the optical constants of the M-O layers. For the air/M-O/reflector configuration, the Ken rotation phi(k) oscillates as a function of the M-O layer thickness and approaches a constant as the thickness d-infinity. If the M-O layers an semitransparent and weakly magnetic, the apparent Kerr rotation can be expressed as <(phi)over tilde (k)> = e(2)<(phi)over tilde'(F)> . For ultrathin metallic magnetic bilayered films the Ken rotation is proportional to the M-O layer thickness and the enhancement factor is a function of the optical constants of the M-O layer and NM reflector. The magneto-optics of a Co spinel ferrite film, Co/Cu, Fe-Ni/Cu, and Co/Si structures have been studied experimentally, (C) 1997 American Institute of Physics.
