Fundamental Studies of Magnetic Materials

该研究项目是磁学和材料磁性领域的多机构科学合作项目。它涉及代表8个机构的10名联合首席研究员。这项科学工作结合了新的材料合成技术，包括分子束外延、先进的结构测定方法、新的自旋敏感光谱技术和最先进的电子结构计算。该项目的主要重点是继续开发和运行自旋极化光电发射装置，该装置基于安装在布鲁克海文国家同步加速器光源上的波动器插入装置的高通量辐射。本研究的主要目的是促进我们对物质磁性行为的理解，重点是新材料，包括表面，超薄外延层，调制结构和超晶格。一个同样重要的目标是培养学生和博士后在多学科研究活动中的能力。材料合成、自旋敏感电子能谱和第一性原理计算在一个协调的研究项目中的结合，为在各种领域获得新的科学知识提供了绝佳的机会，包括外延生长、相变、磁学和新型磁性材料。该项目还将作为固态物理和其他学科的多研究者研究工作的原型，这些学科需要一个协调的团队方法，将科学人才和资源结合起来，超出了单个设施或机构所能提供的范围。

This research project is a multi-institutional scientific collaboration in the field of magnetism and the magnetic properties of materials. It involves 10 co-principal investigators representing 8 institutions. This scientific effort combines novel materials synthesis techniques including molecular beam epitaxy, advanced structure determination methods, new spin-sensitive spectroscopic techniques and state-of-the-art electronic structure calculations. The major focus of this project involves continued development and operation of a spin- polarized photoemission facility based on high-flux radiation from an undulator insertion device installed at the National Synchrotron Light Source at Brookhaven National Laboratory. The primary objective of this research is to advance our understanding of the magnetic behavior of matter with emphasis on novel materials including surfaces, ultra-thin epitaxial layers, modulated structures and superlattices. An equally important object is to train students and post doctoral associates in multi-disciplinary research activity. The combination of materials synthesis, spin-sensitive electron spectroscopies and first-principles calculations in a coordinated program of research offers outstanding opportunities for gaining new scientific knowledge in a variety of fields including epitaxial growth, phase transformations, magnetism, and novel magnetic materials. This project will also serve as a prototype for multi-investigator research efforts in solid state physics and other disciplines that require a coordinated team approach, combining scientific talent and resources that extend beyond what is available at a single facility or institution.
