Caption: Spintronics at the atomic level. Substitution of magnetic atoms (manganese) into a semiconductor (gallium arsenide) creates the material for future electronics. Spins of the magnetic atoms interact via a cloud of electrons, which can be visualized using a scanning tunneling microscope. The image is a composite of microscopic visualization of electron cloud together with a model of the gallium arsenide crystal structure.
