We have been awarded beamtime for soft-xray magnetic scattering studies of multilayer systems at the National Synchrotron Light Source (NSLS) at Brookhaven in the USA. Unlike European Facilities such beamtime does not come with money to support travel to the facility. The experiments form part of our ongoing and highly successful joint programme on magnetic scattering between Leeds and ISIS. The grant request is for travel and subsistence funds only to allow a team of three people to travel to Brookhaven for five weeklong periods in order to operate the experiment 24 hours a day. A unique aspect of this proposal is that we intend to make electrical measurements of our samples whilst they are undergoing the scattering studies / this will lead to a deeper understanding of the relationship between the physical and magnetic microstructures of our samples, which will be revealed by the x-ray measurements, and their spin-dependent electronic functional properties.

我们在美国布鲁克海文国家同步加速器光源(NSLS)的多层膜系统软X射线磁散射研究中获得了BEAM TIME奖。与欧洲设施不同，这样的波束时间不会带来资金来支持前往设施的旅行。这些实验是我们正在进行的关于利兹和伊斯兰国之间磁散射问题的非常成功的联合方案的一部分。拨款申请是用于旅行和生活费用，只允许一个三人小组在布鲁克海文旅行五周，以便一天24小时运行这项实验。这一提议的一个独特方面是，我们打算在样品进行散射研究的同时对其进行电学测量/这将使我们对样品的物理和磁性微结构之间的关系有更深入的了解，这将通过X射线测量揭示，以及它们与自旋相关的电子功能特性。
