摘要：

Au/Co(4 ML)/Au sandwiches grown on molybdenite substrates and showing strong perpendicular anisotropy have been studied by transmission electron microscopy (TEM). The growth characteristics and relaxation mechanisms of the ultrathin magnetic layers have been determined by combining information given in plan view and cross-sectional TEM specimens micrographs. In-plane and out-of-plane elastic strains in the Co layer have been deduced from the measurement of moire fringes spacing and atomic planes spacing obtained by high-resolution imaging followed by image processing. Our results give evidence for an island growth mode of the Co layer and a volume expansion of the cobalt lattice. They are analysed through the comparison with results obtained by other experimental techniques and in particular, in noncovered cobalt layers.
