There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: : We measure magnetic motion in single nanometer scale Ni particles in real time, using a technique of spin-to-charge conversion in quantum dots. Extraordinary long spin relaxation time is confirmed (~10 msec), similar to spins in nonmagnetic quantum dots. Highly sensitive yet simple technique to study magnetic properties developed, as an alternative to SQUIDs (superconducting quantum interference technique). Confirming strongly underdamped magnetic dynamics opens a different path to study macroscopic quantum effects in magnetization and spin transfer.
Bio: Dr. Dragomir Davidovic studies fundamental properties of condensed matter systems, by nanofabrication, transport measurements, and simulations and analysis. He received a B.S. Physics from Belgrade faculty of science, a PhD at the Johns Hopkins University in 1996, and a post-doctorate at Harvard University. Dragomir Davidovic is a Packard fellow. His research focuses on quantum properties in nanoscale structure with an emphasis on magnetism.
