Making a Magnetic Moment in a Split Picosecond

(PhysOrg.com) -- A wide range of phenomena in nature and technology depend on changes that occur in a material after it is illuminated with visible light. A well-known example is photosynthesis, where successive excitations by photons (light particles) leads to the production of oxygen from water. Other, more application-specific examples are solar cells and photocatalysis. Current research involves the study of iron molecular complexes, such as iron bipyridine, that after photoexcitation turn from nonmagnetic to magnetic.
