My principal interest is the structure of magnetic nanostructures engineered from ferromagnetic/ non-ferro- magnetic layers epitaxially grown on semiconductors. The correct interpretation of the magnetic behaviour in such systems- the magnetic anisotropy and interlayer coupling- is strongly dependent on the nature of the interface between layers, the strain in the layers and the extent of any interdiffusion or reaction between layers and substrate. The same factors are important to improving spintronic devices which depend upon the efficiency with which an electron carries its spin through a metal-semiconductor interface.

我的主要兴趣是在半导体上外延生长的铁磁/非铁磁层所设计的磁性纳米结构。对这种体系中磁性行为的正确解释——磁性各向异性和层间耦合——在很大程度上取决于层间界面的性质、层内的应变以及层与基体之间任何相互扩散或反应的程度。同样的因素对于改进自旋电子器件也很重要，这些器件依赖于电子通过金属-半导体界面携带自旋的效率。
