Pb在Cu（111）上的沉积改变了CoyCu超晶格的磁性。表面活性剂的使用诱导Co的逐层生长并延迟fcc到hcp结构转变。因此，易磁化轴保持垂直于与Pb生长的CoyCu膜的平面。另一方面，消除与表面活性剂生长的Cu间隔层中的孪生允许在CoyCu超晶格中观察到完整的反铁磁耦合的面内和面外磁化。[S0031-9007（96）00377-8]
Deposition of Pb on Cu(111) prior to the growth of CoyCu superlattices changes the magnetic properties of the latter. The use of a surfactant induces layer-by-layer growth of Co and delays the fcc to hcp structural transition. As a consequence, the easy axis of magnetization remains perpendicular to the plane for CoyCu films grown with Pb. On the other hand, the elimination of twinning in the Cu spacers grown with surfactants allows the observation of complete antiferromagnetic coupling in CoyCu superlattices for both in-plane and out-of-plane magnetization.
