Clear & Present Superparamagnet

Abstract:
Albert E. Stiegman has a knack for designing useful materials in the guise of pretty colored glasses. Over the years, he has fabricated porous silica gels that fluoresce on their own, or that turn vibrant oranges, yellows, and greens when they're exposed to pollutants. His latest find may be the most provocative yet: a beautiful purple glass impregnated with nanoscale-sized magnets. Not only is the bulk material transparent and superparamagnetic--that is, each nanoparticle behaves like a single independent magnetic domain--but its magnetic properties can be tuned by doping it with ammonia and exposing it to light
