Miller, Joel Steven | Three-dimensional network-structured cyanide-based magnets | Introduction Magnets based on metal oxides have been important for hundreds of years. Magnetite, Fe3O4, Co-doped (y)-Fe2O3, and CrO2 are important examples. The oxide (O2-) bridge between the magnetic metal ions has filled p orbitals (Figure 1a) that provide the pathway for strong spin coup... | Magnetic; Ferrimagnetic; Magnetization | 2000 |

Miller, Joel Steven | Optical control of magnetization in a room-temperature magnet: V-Cr Prussian blue analog | We report reversible photoinduced magnetic phenomena for a V-Cr Prussian blue analog (Tc~350 K). This molecule-based magnet exhibits a decrease in magnetization upon illumination with UV light (λ~350 nm) and reaches a metastable state that has a long lifetime at low temperatures (>106 s at 10 K). ... | 2010-09 | |
