摘要：

The structure of a 20 angstrom thin Co layer embedded between Fe layers grown with molecular beam epitaxy on MgO is determined with ion beam channeling. From the position and the ratio of the widths of the angular yield profiles for different crystallographic directions, we show that Co is forced in the metastable body centered cubic structure. The presence of tetragonal distortion in the Co layer is observed.
