Electrical control of single atom magnets
9 December 2013
The energy needed to change the magnetic orientation of a single atom
– which determines its magnetic stability and therefore its usefulness
in a variety of future device applications – can be modified by varying
the atom’s electrical coupling to nearby metals.
This striking result was published today in the journal Nature Nanotechnology by an international group of scientists working at the London Centre for Nanotechnology (LCN) at UCL, the Iberian Nanotechnology Laboratory (Portugal), the University of Zaragoza (Spain), and the Max Planck Institute of Microstructure Physics (Germany).
