Abstract:A ferrofluid has been prepared by thermal decomposition of Fe(CO)5 in an organic liquid. Mössbauer spectroscopy and x-ray diffractometry studies show that the ferrofluid contains small particles of a metallic glass. The particles are only partly oxidized even after exposure of the ferrofluid to air at room temperature for 30 days.
