C. Prieto et al., STRUCTURAL BEHAVIOR OF CO CU MULTILAYERS STUDIED BY X-RAY-ABSORPTION SPECTROSCOPY/, Journal of magnetism and magnetic materials, 161, 1996, pp. 31-36
The study of the Co environment in Co/Cu multilayers by X-ray absorpti
on spectroscopy shows that a significant change in the cobalt environm
ent occurs when the Cu thickness is smaller than 20 Angstrom. Data are
explained in terms of an island structure of the Co layers. This resu
lt agrees with a non layer-by-layer growth mode of cobalt over copper.
The temperature dependence of the magnetization presents also differe
nces for these samples according to the structural behavior.
