Visualizing Spin Currents with X-ray Microscopy

Pure spin currents and electrical currents with a net magnetic spin moment are fascinating from a fundamental as well as applied perspective. They offer the possibility to manipulate the magnetization of a magnetic "free layer" in a device with much lower power consumption than before. The effects of spin currents have been studied intensively using transport measurements. However, from a fundamental point of view it is also often interesting to “see” the currents directly on a microscopic scale. Soft x-ray microscopy is an excellent tool for this purpose and in my talk I will give several examples of how to employ this tool to learn more about spin transport on the nanoscale using direct observations.
