摘要：

The magnetic properties of Co/Cu multilayers were investigated from 5 to 380 K and analyzed in terms of the interface magnetism and mean-field model. The interface, which is about 1.2 angstrom thick, is nonmagnetic at room temperature and becomes magnetic at 5 K with the average magnetization of 40% of the pure Co magnetization. The samples of X angstrom Co/10 angstrom Cu behaved superparamagnetically as X ranged from 4 to 6.5 angstrom and did not show superparamagnetic behavior for thinner or thicker Co layer thickness.
