EETimes.com - IBM develops method to control atom-scale magnetism: "MANHASSET, N.Y. — IBM scientists have developed a new technique, called spin-excitation spectroscopy, to explore and control magnetism at its fundamental atomic level.

The method promises to be important not only in the quest to understand the operation of future computer circuit and data-storage elements as they shrink toward atomic dimensions, but also to lay the foundation for new materials and computing devices that leverage atom-scale magnetic phenomena."
