They are exploring the magnetic and structural behavior of rare earth superlattices and buried layers. These systems can now be grown with a, b or c axes perpendicular to the plane. They seek to understand the orientation-dependent epitaxial phase diagrams of the antiferromagnetic rare earths such as Dysprosium, Erbium, Holmium, Terbium, which depend strongly on magnetoeslastic strains in the presence of epitaxial "clamping". The way different types of spacer layers couple successive magnetic layers into superlattices with modified properties is also of central interest. These phenomena are pursued using novel materials synthesis, by magnetic and mechanical measurements, and by the techniques of light, x-ray and neutron scattering.

他们正在探索稀土超晶格和埋藏层的磁性和结构行为。这些系统现在可以用垂直于平面的a、b或c轴生长。他们试图理解反铁磁性稀土（如镝、铒、钬、铽）的取向依赖外延相图，这些稀土在外延“夹紧”的存在下强烈依赖于磁弹应变。不同类型的间隔层将连续磁层耦合成具有修改性质的超晶格的方式也是中心兴趣。这些现象是通过新材料合成、磁和机械测量以及光、x射线和中子散射技术来追求的。
