Scientists from Ohio University and the University of Hamburg has captured images of atomic spin in action for the first time. They have used a custom-built microscope and cobalt atoms. The team repositioned individual cobalt atoms on a surface that changed the direction of the electrons' spin. Images captured by the scientists showed that the atoms appeared as a single protrusion if the spin direction was upward, and as double protrusions with equal heights when the spin direction was downward.
