采用独特的超低温、超高精度 测量系统，他们一直在确定如何以及为什么 碱金属的输运性质偏离 从目前的自由电子金属模型预期的行为。 他们正试图确定这些异常现象是否可以 通过修改自由电子模型来解释，或者 他们需要更多的外来替代品，如电荷密度， 波（CDW）。 他们正在研究垂直于 铁磁/正常和铁磁/超导金属 在用四枪溅射系统制备的样品中， 在MSU和样品由分子束外延（MBE）在 University of Illinois.

Using a unique, ultra-low-temperature, ultra-high-precision measuring system, they have been determining how and why the transport properties of the alkali metals deviate from the behavior expected from current models for free-electron metals. They are attempting to determine whether these anomalies can be explained by modifications of free-electron models, or whether they require more exotic alternatives such as a Charge-Density- Wave (CDW). They are studying electrical transport perpendicular to ferromagnetic/normal and ferromagnetic/superconducting metal interfaces both in samples made with a four-gun sputtering system at MSU and samples made by Molecular Beam Epitaxy (MBE) at the University of Illinois.
