Physicists Pin Down Spin of Surface Atoms
September 12, 2007
University of California, Berkeley physicists have successfully measured the atomic spin of an isolated atom, one of the necessary steps on the road to quantum computers and spintronics devices. Using a scanning tunneling microscope with a spin-polarized tip, Michael Crommie and colleagues mapped the surface topography and the surface energy levels to determine the spin of adatoms--the first time this has been measured directly.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
