The anisotropic photo-induced magnetization
depends on the relative strength of dipolar field
(HD) produced by primordial spins compared to
the external magnetic field (HE).
New thin-film magnets based on Prussian blue
analogs were generated and discovered to possess
unusual anisotropic photo-induced magnetism.

Education This work was conducted as a close
collaboration between physics and chemistry
groups that are dedicated to the training of
young researchers. Three graduate students
(Park, Frye, and Lane) and two international
scholars (Huh, South Korea, and Cižmár, Slovakia)
played key roles in the research. Erik Cižmárs
participation was made possible by a NSF-NATO
Postdoctoral Fellowship (DGE-0209410). The young
researchers receive interdisciplinary training
that includes expertise in SQUID magnetometry
made possible by NSF DMR-0113714.
Social Impact The combined physics/chemistry
studies perform molecular-level manipulation
leading to new solid-state structures. This
bottom-up approach yielded a new nano-sized
magnetic thin-film possessing unusual
photo-induced magnetism. This exotic
functionality is optically and orientationally
controlled and provides an prototype for new
magnetic devices.
