Spin polarimetry - An unpolarised electron beam is scattered at a magnetic film, resulting in a polarised beam.Spin electronics is based on utilising the electron spin for novel and improved electronic devices. The success of spintronics ultimately depends on our ability to precisely control the polarisation of electrons transported within the actual thin film structure. At present electrical measurements are principally used to assess the quality and performance of magnetic thin film devices. In a revolutionary approach we measure the spin polarisation of freely scattered electrons from atomically clean surfaces and interfaces using spin polarimetry.
