Abstract

We have studied the effects of placing Co/Pt multilayers on dysprosium-iron-garnet doped with bismuth and aluminum. The garnet was deposited by RF-magnetron sputtering and crystallized by rapid thermal annealing. The Co/Pt multilayers were then deposited by DC-magnetron sputtering. The garnet thickness was held constant at 1000 angstroms while the Co/Pt multilayer had the form of [3 angstroms Co/9 angstroms Pt]_n with n ranging from 1 to 16. Coercivities of the samples ranged from about 300 to 2000 Oe. Kerr rotations were as high as 1.8 ° and ellipticities up to 2 ° depending upon the wavelength of light and the number of Co/Pt bilayers. Magneto-optic signal figures of merit are determined for several of these composite systems.
