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.
