Nanophysicists Find Unexpected Magnetic Effect
April 29, 2009
In new research appearing this week in Nature, physicists at Rice University and the University of Alicante have found that single-atom contacts made of ferromagnetic metals like iron, cobalt and nickel, exhibit behavior consistent with the Kondo effect. The unexpected behavior appears to arise due to the tendency of the electrons on the last atom of material to align their spin in a countervailing direction from that of neighboring electrons.
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) 2017, 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.
