Physicists tailor magnetic pairings in nanoscale semiconductors
Electrons love to zip around metals such as copper, especially if the metal is cooled to temperatures near absolute zero. But if they encounter a magnetic atom (say, iron) during their travels, the electrons will try to "screen," or cancel out, the magnetic atom's spin alignment by pairing with it. This pairing modifies the flow of... view more... (2007-03-15)
Researchers Create Catalysts for Use in Hydrogen Storage Materials
