摘要：

A structural analysis in the Co10Cu90 granular alloy prepared by the melt spinning technique has been carried out using Co-59 NMR method. Two magnetic phases have been found in the as quenched sample. A prevailing phase (involving 90% of the observed Co atoms) is a population of small, strained FCC Co precipitates. A second phase is a soft magnetic FCC CoCu alloy with average Cu concentration of about 10%. (C) 1999 Elsevier Science B.V. All rights reserved.
