Workshop
1: Nanomagnetism
Co-organizers:
Dongqi Li and Seth Darling
Nanoscale
magnetic systems, such as nanoparticles and
ultrathin films, display properties distinct from
bulk materials. Burgeoning industrial applications
such as spintronics and magnetic recording demand a
deeper understanding of these systems. Hence, their
preparation and characterization are both ongoing
challenges as traditional techniques run into
intrinsic limitations. In this workshop,
fundamental aspects of magnetism in reduced
dimensionality, as well as state-of-the-art
fabrication techniques, are discussed. This
discussion highlights the use of various x-ray
based approaches for exploring nanomagnetic
systems.
