摘要: Abstract We report variations between 10.7 A (Cu0.965Ge0.035) and 15.8 (Cu0.81Ni0.19) of the periodicity oscillatory interlayer exchange coupling for (111)-oriented CuXCo multilayers. These results are correlated with topology Fermi surface CuNi CuGe alloys. They confirm that is due to electronic states stationary q-vectors passing through neck spacer layer surface.
