小行星9704196 该奖项是为了部分支持一个新的超高真空室，用于纳米结构磁性的研究。 该室将是一个移动的独立系统，将位于同步辐射中心，威斯康星州大学。 它将被耦合到三个现有的专门用于测量磁性圆二色性，自旋分辨光电子能谱和x射线共振磁散射的腔室之一。 这些方法分别提供了元素分辨的磁矩、自旋分裂能带和磁粗糙度. 拟议的生长室将提供各种各样的磁性纳米结构，以及这些磁性测量表征的形态。 特别强调将放在溅射沉积的磁性纳米结构和溅射沉积和蒸发纳米结构之间的比较。 %该奖项是为了部分支持一个新的超高真空室，用于纳米结构磁性的研究。 该室将是一个移动的独立系统，将位于同步辐射中心，威斯康星州大学。 它将被耦合到三个现有的专门用于测量磁性圆二色性，自旋分辨光电子能谱和x射线共振磁散射的腔室之一。 这些方法分别提供了元素分辨的磁矩、自旋分裂能带和磁粗糙度. 拟议的生长室将提供各种各样的磁性纳米结构，以及这些磁性测量表征的形态。 特别强调将放在溅射沉积的磁性纳米结构和溅射沉积和蒸发纳米结构之间的比较。 所获得的基本知识和腔室的可用性将促进磁性器件的开发，并将导致在理解磁性薄膜和界面方面的重大基础研究进展。 ***

9704196 Lagally This award is for the partial support of a new ultra-high vacuum chamber for the investigation of nanostructure magnetism. The chamber will be a mobile self-contained system that will be located at the Synchrotron Radiation Center, University of Wisconsin. It will be coupled to one of three existing chambers built specifically for measuring magnetic circular dichroism, spin-resolved photoelectron spectroscopy, and x-ray resonant magnetic scattering. These methods provide element resolved magnetic moments, spin- split energy bands, and magnetic roughness, respectively. The proposed growth chamber will provide a wide variety of magnetic nanostructures with well characterized morphologies for these magnetic measurements. Special emphasis will be placed on sputter deposited magnetic nanostructures and comparisons between sputter deposited and evaporated nanostructures. %%%% This award is for the partial support of a new ultra-high vacuum chamber for the investigation of nanostructure magnetism.
