摘要：

Magneto-optical (MO) Kerr effect of micro-cavities composed of a Co thin film and SiO2/SiN multilayer films was investigated theoretically and experimentally. The micro-cavity structure was found to be very effective for enhancing the MO Kerr effect: the MO Kerr rotation angle exceeding 10 degrees at a designated wavelength of light was obtained, the value of which is more than 100 times larger than that of a Co single-layer film. The large MO Kerr effect is caused by the localization of light originating from the multilayer structure. (C) 1999 Elsevier Science B.V. All rights reserved.
