Description

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
