Imaging and manipulating the spin direction of individual atoms

D Serrate, P Ferriani, Y Yoshida, SW Hla… - Nature …, 2010 - nature.com
Single magnetic atoms on surfaces are the smallest conceivable units for two-dimensional
magnetic data storage. Previous experiments on such systems have investigated
magnetization curves,, the many-body Kondo effect, and magnetic excitations in quantum
spin systems,, but a stable magnetization has not yet been detected for an atom on a non-
magnetic surface in the absence of a magnetic field. The spin direction of a single magnetic
atom can be fixed by coupling it to an underlying magnetic substrate via the exchange …

Single magnetic atoms on surfaces are the smallest conceivable units for two-dimensional
magnetic data storage. Previous experiments on such systems have investigated
magnetization curves1, 2, the many-body Kondo effect3, 4 and magnetic excitations in
quantum spin systems5, 6, but a stable magnetization has not yet been detected for an atom
on a non-magnetic surface in the absence of a magnetic field. The spin direction of a single
magnetic atom can be fixed by coupling it to an underlying magnetic substrate via the …
