Workshop #1 at the NSLS Users' Meeting

Nanomagnetism: Materials and Probes

Location: Bldg. 555, Chemistry, Hamilton Room

Date: Monday, May 23, 2005

Organizers:
L. H. Lewis (BNL, MSD/CFN), (lhlewis@bnl.gov)
C.-C. Kao (BNL, NSLS), (kao@bnl.gov) 

Description: The nanometer is the natural length scale of magnetism. Advances in materials synthesis and nanofabrication technology in recent years have made it possible to create a wide range of nanomagnetic systems with unprecedented precision. These novel magnetic systems are used as model systems for the testing of long standing theories in magnetism, as well as for the exploration of new device concepts and applications. In parallel, synchrotron radiation, with its unique polarization properties, tunability and time structure, has become an indispensable tool for the study of magnetism and magnetic materials. The objective of this workshop is to provide an overview of latest synchrotron characterization techniques, as well as new materials concepts for magnetic materials, with the goal of presenting an up-to-date snapshot of forefront issues in nanomagnetism, and promoting collaboration between researchers in this exciting area and synchrotron experts.
