Magnetic interactions in MBE grown Fe/x Au/Tb trilayers

• Indirect exchange coupling between Fe and Tb layers showed oscillatory behaviour through Au layer as a function ofits thickness. Trilayers, prepared in the MBE system, were characterized with different experimental tools. Results are analysed to reconstruct the dynamics of Fe and Tb magnetic moments. For the first time, the change of sign in magnetic interaction is shown for Fe/Au/Tb system.
