Abstract

Recently, we have combined measurements of the magneto-optic Kerr effect with Brillouin light scattering (BLS) to compare the magnetic properties of molecular beam epitaxy (MBE)-grown Au/Co/Au films on 4°-miscut Si(1 1 1) with those of films grown on non-miscut Si(1 1 1). In both types of samples, the Kerr measurements indicate strong perpendicular magnetic anisotropy. However, the spin wave frequencies determined by BLS for the samples on 4°-miscut wafers exhibit anomalous behavior. We will discuss such BLS measurements on a variety of ultra-thin MBE-grown layered samples, showing the relationship of the magnetic properties to the evolving structure of the films.
