Nanoscaled Fe particles embedded in a double-oxide matrix were obtained by synthesizing a zinc–aluminium layered double hydroxide intercalated with a hexacyano Fe(III) complex under vacuum thermal annealing. Chemical and structural properties were investigated by Fourier transform infrared spectroscopy, x-ray photoemission spectroscopy, x-ray diffraction and transmission electron microscopy. The magnetic properties of the Fe nanoparticles were investigated using a SQUID magnetometer. Our measurements indicate a system of weakly interacting magnetic nanoparticles that are arranged in a multidomain state at low temperature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
