Abstract

The rise of spintronics has been closely linked with the development of instrumentation in nano-characterization over the past 20 years. The experimental side of spintronic research today has moved to a point where the paramount urgency is to use materials of the highest perfection and homogeneity as well as analysis tools with atomic sensitivity. Such criteria require usually exclusive techniques, dedicated equipment, and extreme physical conditions, such as ultrahigh vacuum, low temperatures, high fields, etc. This chapter presents some of the most advanced experimental tools, i.e., synchrotron-based magnetic dichroism techniques, which have facilitated the studies of many cutting-edge subjects of spintronics, such as the heterojunction interfacial magnetism, magnetic proximity effect, magnetism in diluted magnetic semiconductors (DMSs), doped topological insulators, half-metallic alloys, magnetic domain structures, and spin transfer torque (STT) effect.
