Paper Abstract

A procedure is described for the design of quadrilayer structures which enhance the polar Kerr effect in magneto-optic recording media. An essential feature of the method is a systematic approach enabling phase-optimization to be achieved resulting in the elimination of the undesirable effects of parasitic Kerr ellipticity. Examples are presented based on the Co/Pt superlattice and amorphous TbFeCo. The spectral and angular performance of fabricated devices is compared with theory.
