Gl. Zhang et al., IRON NANOPARTICLES GROWN IN A CARBON-ARC DISCHARGE, Nuovo cimento della Societa italiana di fisica. D, Condensed matter,atomic, molecular and chemical physics, biophysics, 18(2-3), 1996, pp. 281-285
Iron particles, encapsulated by graphite layers, were produced by mean
s of the Kratschmer are discharge method in an iron pentacarbonyl atmo
sphere. The Mossbauer effect is dominated by the vibration of the part
icles as a whole. Superparamagnetism is dominant for iron oxide partic
les. No endohedral iron fullerenes were observed, contrary to a previo
us report.
