Supercomputing, experiment combine for first look at magnetism of real nanoparticle
A multi-institution team simulated, for the first time, atomic-level magnetic properties in regions of a real nanoparticle based on experimental data. UCLA and Berkeley Lab's cutting-edge imaging and 3-D reconstruction techniques combined with the 27-petaflop Titan supercomputer at OLCF and the award-winning LSMS magnetic structure code, developed at ORNL, enabled researchers to model the magnetic properties of over a thousand atoms of an iron-platinum nanoparticle -- a material that has applications for next-generation magnetic storage devices.
