| Recently we completed the very first and detailed perturbed angular correlation investigation on MBE-grown very thin film multilayers. The present paper aims to show that otherwise rather unaccessible but unique information on the (interface) magnetism could be obtained. For the Fe/Cr(1 0 0) multilayer system we observe, below a critical Cr thickness of 5.0 nm, a collapse of the spin-density-wave ordering in chromium. While the magnetization in the Fe-layer is in-plane, the Cr magnetization in thicker layers is out-of-plane. In the Fe/Co (1 -1 0) system, the observation of transferred magnetic hyperfine field satellites and their temperature dependence leads to the determination of an oscillating magnetic moment profile at the Fe/Co interface as well as a structure model for the superlattice. |
