Using hydrogen ions to manipulate magnetism on the molecular scale
(PHYSorg.com Physics)

A team of researchers from the Massachusetts Institute of Technology (MIT) and the U.S. Department of Energy`s (DOE) Brookhaven National Laboratory has determined how to use hydrogen ions, `pumped` from water in the air at room temperature, to electrically control magnetism within a very thin sample of a magnetic material. This approach for manipulating magnetic properties could speed up advances in computing, sensors, and other technologies.
