Abstract
In this article the magnetooptics of magnetooptical (MO) layered structures have been studied theoretically and experimentally. For the air/MO/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 MO layers are semitransparent and weakly magnetic. The interference factor e(1) is a function of the optical constants and the MO layer thickness d, and thelight wavelength. In these structures, the apparent Faraday rotation consists of two parts. One oscillates as a function of the MO 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 MO layers. For the air/MO/reflector configuration, the Ken rotation phi(k) oscillates as a function of the MO layer thickness and approaches a constant as the thickness dinfinity. If the MO 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 MO layer thickness and the enhancement factor is a function of the optical constants of the MO layer and NM reflector. The magnetooptics of a Co spinel ferrite film, Co/Cu, FeNi/Cu, and Co/Si structures have been studied experimentally, (C) 1997 American Institute of Physics.
