Abstract
The magnetocrystalline anisotropy energy in bcc Fe2m-1/fcc Au5 (001) superlattices (m = 1-12) has been calculated from first principles by using a relativistic electronic band-structure method. The calculated magnetocrystalline anisotropy energy in these Fe/Au superlattices is found to oscillate in both sign and magnitude with the Fe slab thickness with a period of about ten monolayers. The origin of this anisotropy oscillation is discussed.Keywords
