  2. Prussian Blue Analogs: Persistent Photoinduced Magnetism in Thin Films, Nanoparticles, and New Composites Daniel M. Pajerowski and Mark W. Meisel, Physics, University of Florida Justin E. Gardner,Franz Frye, and Daniel R. Talham, Chemistry, University of Florida This work was conducted as a close collaboration between physics and chemistry groups, especially the UF Chemistry Group lead by Daniel R. Talham (DMR-0543362), that are dedicated to the training of young researchers. Three graduate students (Pajerowski, Gardner, and Frye) played key roles in the research, while four undergraduates [Justin Cohen (UF), Jaron Swift (Prairie View A&M University), Miguel Bencomo (University of Texas at El Paso), and Peter Lunts (Indiana University)] supported by the NSF via this grant, the UF Physics REU Program, and the NHMFL REU Program, have worked in the group on these and related experiments. Our activities also include participation of a research team at P.J. Šafárik University in Košice, Slovakia. Education The combined physics/chemistry studies perform molecular-level manipulation leading to new solid-state structures. The “bottom-up” approach allows the materials to be combined in novel arrangements that are studied experimentally and numerically. The results enable tuning of the magnetic properties that can be optically and orientationally controlled, thereby paving the road to new magnetic devices. Social Impact One of the crucial instruments used to perform this research is a SQUID magnetometer, which was made possible by NSF DMR-0113714. In order to perform in situ studies of the anisotropic nature of the photoinduced magnetism of thin films, we have designed, constructed, and operated a probe that, for the first time, combines optical fibers with a low-temperature, rotational stage. This device has been described the literature. Infra- structure Supported by NSF DMR-0701400, with additional support from the UF Physics REU Program, DMR-0552726, and the NHMFL REU Program, DMR-0654118.
