Spin and angle resolved photoelectron spectroscopy has become very important with the increased attention for topological insulators. In this class of materials the electronic structure of the surface is significantly different than from the bulk. An insulating material can have a conducting surface. Topological insulators with bands crossing the Fermi level at the surface can have spin locked states which yield in a spin polarized charge transport at the surface. The surface properties are highly sensitive for magnetic fields.
