Scientific American 50
Scientists take inspiration from nature and instill novel magnetic properties.
 
Congratulations to our author, Prof. Sergej Demokritov (University of Muenster, Germany), in winning the Scientific American 50 award for outstanding research, business and technological leadership.

It was thought that the only way to see the exotic state of matter known as a Bose-Einstein condensate-in which a collection of particles essentially behaves as one superparticle-involved forbidding, near-absolute-zero cold. Sergej Demokritov of the University of Muenster in Germany and his colleagues were the first to create such condensates at room temperature. Demokritov used small, ephemeral packets of magnetic energy known as magnons, which he generated in yttrium-iron-garnet films by exposing them to microwaves. Magnons are far less massive than atoms and thus can form condensates at much higher temperatures. - Original article published in

Scientific American and written by Graham P. Collins and Charles Q. Choi.

Prof. Demokritov is the editor of Spin Wave Confinement.
