Abstract

Nanoparticles of rubidium cobalt hexacyanoferrate were synthesized using the organic ligand poly(vinylpyrrolidone) (PVP). The particles, with composition Rb_1.8Co₄[Fe(CN)₆]_3.2 · nH₂O determined from CHN combustion analysis and ICP-MS, have an average size of 10 nm ± 2 nm. Similar to bulk samples, the nanoparticles show evidence of ferrimagnetic ordering in DC magnetization below T_C ∼ 15 K, although the transition is broadened due to the small particle size and its dispersion. Upon illumination with white light at 5 K, the field-cooled DC magnetization of these particles increased 40%.
