State of the art molecular beam epitaxy techniques are used to synthesize new magnetic multilayer films. Both metals and oxygen- based materials are being prepared. The basic issues to be addressed are: the role of epitaxial strain in determining the phase diagram of thin magnetic single crystals; the propagation of magnetic order and excitations through selected multilayer systems; coherent electronic structure, including interfacial and magnetotransport effects; and low-dimensional behavior in structural ordering and magnetism using surfaces and interfaces with tailored periodicities.

分子束外延技术被用来合成新的磁性多层膜。金属和氧基材料都在制备中。要解决的基本问题是：外延应变在确定薄磁性单晶相图中的作用；磁序和激发通过选定的多层系统的传播；相干电子结构，包括界面和磁输运效应；以及使用具有定制周期的表面和界面的结构有序和磁性的低维行为。
