4. Description Abstract

The magnetic anisotropy results of Ni81Fe19 multilayers, prepared by DC sputtering in ultra high vacuum, were described on the basis of existing models. It is shown that magnetoelastic anisotropy energies Kme of the Ni81Fe19/W90Ti10 multilayers which have fcc (111) perfectly flat interfaces can be expressed with biaxial modulus, magnetostriction and lattice mismatch. In the incoherent state, the residual strain gives rise to a magnetic anisotropy which is proportional to the reciprocal of the magnetic layer thickness. The influence of roughness would decrease the anisotropy contribution.
