Nanomagnetics

The keys to all electronic devices are intricate magnetic nano-structures (see figure). As the dimensions of individual magnetic elements shrink below 100 nm, their magnetic microstructures become more complex, eventually shrinking to smaller than 10 nm. As a result, the physics of the switching mechanisms of the elements, the thermal stability of their magnetization, and interactions between elements must all be re-examined. This will require new synthesis and fabrication processes, new materials with tailored nanoscale properties, and especially new experimental techniques that are sensitive to the magnetization of nanoscale materials.

The high brightness synchrotron radiation of NSLS-II is critical to advancing the field of nanomagnetics. NSLS-II will enable element-specific magnetic measurements with nanometer resolutions and extremely high sensitivity, studies of the magnetic structure and behavior of individual nanomagnetic elements, and studies of interactions among collections of elements. The detection of the magnetic structure of buried interfaces and induced moments in non-magnetic metals and semiconductors will become possible.

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE’s Office of Science by Brookhaven Science Associates, a limited-liability company founded by Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
