Neutron diffraction on amorphous iron powder

Neutron-diffraction experiments have been carried out on amorphous iron powder prepared from the ultrasonic irradiation of Fe(CO)₅. The structural information from the shape of the radial distribution function is consistent with the random-packing-model (RPD) calculations previously made for films of amorphous iron. The atomic magnetic moment of iron in the amorphous bulk phase has been obtained and its value is close to that of liquid iron. A comparison is made between the present μFe value and those previously extracted by extrapolation from the concentration dependence of the binary Fe_(1-x){B}ₓ$ metallic glasses.
