Abstract

The purpose of this paper is twofold. First, we describe the adaptation of a variable angle spectroscopic ellipsometer (VASE) to magnetoÃ¢â‚¬Â�optic measurements covering 3000Ã¢â‚¬â€œ8000 Ãƒâ€¦, and 0 to Ã‚Â±8 kOe. Second, we describe application of VASE to determine Kerr rotation and ellipticity for a series of Dy/Co multilayers prepared by sputter deposition. We report spectroscopic ellipsometric and Kerr effect results for samples exhibiting perpendicular magnetic anisotropy, since these are relevant as magnetoÃ¢â‚¬Â�optic recording media.
