摘要：

We created helical magnetic structures by depositing in sequence layers of lanthanum and iron (each 30 Angstrom thick) on a substrate rotating in a fixed field of a few Oe. The magnetic field was sufficient to define the magnetization of each layer during growth without disturbing the magnetization of the layers already formed. As a result, the imprinted helical magnetic structure had a chirality given by the direction of rotation of the substrate; the pitch was given by;the speed of rotation and the rate of deposition. This finding indicates that it is possible to engineer mesoscopic magnetic structures. (C) 1998 American Institute of Physics.
