Abstract
The ratio of the orbital to the spin magnetic moment was determined for both Fe and Co in amorphous Co68Fe24Zr8 layers using x-ray circular dichroism. The investigations were performed on both thick Co68Fe24Zr8 layers as well as on amorphous Co68Fe24Zr8/Al70Zr30 multilayers grown by dc sputtering. Structural characterization was performed using x-ray reflectometry, x-ray diffraction, and transmission electron microscopy. X-ray circular dichroism, x-ray magnetic scattering as well as the magneto-optic Kerr effect were used to characterize the magnetic properties of the amorphous materials. The ratio of the orbital to spin moments in the single CoFeZr-layer sample was 0.012 +/- 0.005 for Fe and 0.078 +/- 0.005 for Co. Substantial reduction in the the ratio of the orbital to spin moments was observed with decreasing CoFeZr-layer thickness.
