Electron Spin in a Cobalt-Iron Alloy (IMAGE) DOE/Argonne National Laboratory Caption Researchers at Argonne have discovered a way to control the direction of electron spin in a cobalt-iron alloy, influencing its magnetic properties. The result could have implications for more powerful and energy-efficient materials for information storage.
