摘要：

Resonant X-ray magnetic scattering experiments have been conducted using circularly polarized light at the Gd L-3, edge on a Fe/Gd multilayer at 300, 150, 100 and 10 K. Specular reflectivity data collected with magnetic fields applied parallel and perpendicular to the plane of scattering confirm the Fe-aligned state at 300 K and twisted states at the low temperatures. At 300K, the Gd spins appear to be distributed with a nonuniform profile along the layer thickness direction. There are at least two distinct twisted states with different magnetic structures at 100 and 10K. (C) 1998 Elsevier Science B.V. All rights reserved.
