摘要：

The magnetic properties of (001)bcc Fe/(001)fcc Ag superlattices grown by molecular-beam epitaxy on (001) GaAs and characterized by reflection high-energy electron diffraction, Auger spectroscopy, and x-ray diffraction are presented. From magnetization (SQUID) and torque experiments, the strong interface uniaxial anisotropy which tends to align the magnetization along the normal to the layers is determined. This interface anisotropy overcomes the demagnetizing field effect when the thickness of the Fe layers decreases below 10 Å. The anisotropy constant Ku is derived from both experiments, which leads to 0.8 erg/cm2 for the interface anisotropy constant Ks.
