Perpendicular Magnetic Anisotropy of Co-Au Multilayers Induced by Interface Sharpening. den Broeder, F. J. A., Kuiper, D., van de Mosselaer, A. P., & Hoving, W. Physical Review Letters, 60(26):2769--2772, June, 1988.
Paper doi abstract bibtex Co-Au multilayers with Co layer thicknesses between 22 and 5 ÅA, prepared by ion-beam sputtering, have an easy-plane magnetic anisotropy. Their saturation magnetization indicates the presence of diffuse interfaces, caused by ion-beam mixing. Annealing of the multilayers at 250-300°C leads to a perpendicular anisotropy for Co thicknesses below about 14 ÅA. This effect is attributed to a stronlgy enhanced interface anisotropy, which is due to sharpening of the interfaces as revealed by x-ray diffraction.
