本研究的目标是以成长为导向的周期性 多层薄膜和表征之间的关系 它们的铁磁特性、界面结构和 混合物. 两个模型实验系统，锰/金和 铁/铂，正在检查中。 直接相关性为 建立在结构和成分的演变之间， 界面和磁性作为函数 选择增量退火处理。 实验 技术包括透射电子显微镜、X射线 衍射、振动样品和扭矩磁力仪，以及 铁磁共振 DC溅射用于产生 多层膜，这是一类新的材料， 拥有其他国家无法达到的独特性能的潜力 材料.

The goal of this research is to grow oriented periodic multilayer thin films and characterize relationships between their ferromagnetic properties, interfacial structure and composition. Two model experimental systems, manganese/gold and iron/platinum, are being examined. Direct correlations are established between the structural and compositional evolution of the interphase interfaces and magnetic properties as a function of selected incremental annealing treatments. Experimental techniques include transmission electron microscopy, X-ray diffraction, vibrating sample and torque magnetometer, and ferromagnetic resonance. DC sputtering is used to create the multilayer films, which are a new class of materials offering the potential of possessing unique properties not attainable in other materials.
