Abstract

We have investigated structural and magnetic properties of CoPt alloy films with strong perpendicular magnetic anisotropy in the thickness range between 100 Angstrom and 400 Angstrom. From a detailed x-ray analysis we find highly (111)-textured CoPt microcrystallites in all samples. STM studies reveal a granular topography with grain diameters of up to 250 Angstrom. Measurements of hysteresis loops yield a saturation field which increases with thickness, and which is consistent with a freely mobile domain model. Brillouin light scattering measurements of the frequencies of the surface and standing spin wave modes yields a bulk exchange constant, which is strongly dependent on the Pt content.
