Opportunities in Nanomagnetism

Samuel BaderSenior Scientist at Argonne National Laboratory and
Scientific Director of the Argonne Center for Nanoscale MaterialsOpportunities in NanomagnetismABSTRACTNanomagnetism is the discipline dealing with magnetic phenomena specific to structures having dimensions in the submicron range. This talk addresses the challenges and scientific problems in this emerging area, including its fabrication strategies, and describes experiments that explore new spin-related behaviors in metallic systems as well as theoretical efforts to understand the observed phenomena. As a subfield of nanoscience, nanomagnetism shares many of the same basic organizing principles such as geometric confinement, physical proximity, and chemical self-organization. These principles are illustrated by means of several examples drawn from the quests for ultrastrong permanent magnets, ultra-high-density magnetic recording media, and nanobiomagnetic sensing strategies. As a final example showing the synergetic relationships to other fields of science, the manipulation of viruses to fabricate magnetic nanoparticles is discussed.**ALL FIRST YEAR MATERIALS SCIENCE MAJORS ARE REQUIRED TO ATTEND**
