New Spin On Graphene Makes It Magnetic 58

intellitech writes "A team led by Professor Andre Geim, a recipient of the 2010 Nobel Prize for graphene, has shown that electric current can magnetize graphene. The researchers found a new way to interconnect spin and charge by applying a relatively weak magnetic field to graphene and found that this causes a flow of spins in the direction perpendicular to electric current, making a graphene sheet magnetised."

    • The team was lead by Michael Fuhrer, not Andrew Geim. The only relationship Geim has to this article is that he received a Nobel for discovering a process to create the material that these researched used (i.e. graphene)
    • It's not electric current that magnetizing the graphene, it's small impurities - specifically, gaps in the lattice. The magnetism is controllable by tuning the number and location of the impurities, which is what makes this potentially useful
    • This doesn't have anything to do with spin, except insofar as all electromagnetism topics do. Spintronics is only mentioned at the very end of the article as something this "could also have interesting applications in".

    It's almost like the summary is describing a different article.
