Enhanced magnetic moment at the interfaces in Fe81Ni19/Co superlattices

The structure and magnetic properties of BCC (0 0 1) oriented Fe81Ni19/Co superlattices grown on MgO(0 0 1) substrates by magnetron sputtering are presented. The variation of magnetic moment with the compn. and with the interface d. was studied. A model in which the magnetic moment per atom at the interfaces is different from that in the interior region was used for the anal. The extension of the interface region is âˆŒ3.5 monolayers and the magnetic moment in this region is enhanced by âˆŒ0.3 ÎŒB/atom, compared to the interior regions. The superlattices form a BCC-like structure with a slight orthorhombic distortion, which gives rise to a weak in-plane uniaxial anisotropy. [on SciFinder(R)]
