Abstract

A method, based on subtractive coloration of high-temperature reduction, has been developed to produce metal precipitates or colloids in oxides. The structure, symmetry, morphology and composition of precipitates were analyzed by analytical elecron microscopy and neutron scattering techniques. From the neutron-magnetic-scattering measurements, the ratio of magnetic to nuclear scattering amplitudes for the (111) precipitate reflection was determined to be 17% below the value for pure nickel, indicating the presence of a magnetically 'dead' layer around the precipitates, a small amount of impurities incorporated into the precipitates, or a small fraction of another phase of nickel.
