title: Formation of cobalt-Prussian Blue nanoparticles in a biopolymer matrix.
abstract: The molecular magnet material, cobalt-Prussian Blue, has been synthesized using chitosan as a morphological structure-directing agent. The strong chelating ability of the biopolymer ensures that the inorganic phase remains nanoparticulate. SQUID magnetometry reveals that the nanoparticles exhibit a sharp ferrimagnetic to paramagnetic transition at 16 K.
