Abstract

A multilayer sample of Dy(47 Å)/Y(40 Å), produced by molecular-beam-epitaxy techniques, is shown to order magnetically in an incommensurate helix that is coherent over several multilayer periods. The magnetic satellite peak has harmonics resulting from the multilayer modulation. The dc magnetic properties are suggestive of a metamagnet.
