MAGNETOSTRUCTURAL STUDY OF NANOSTRUCTURED AND AMORPHOUS BULK ALLOYS (Co-P)(100-x)Cu-x
The work reports a magnetostructural study of bulk nanostructured composite materials Co–P/Cu prepared by dynamic compaction (DC) and uniaxial cold pressing (CP). The initial particles with amorphous and crystalline structure are synthesized by chemical deposition. Magnetic characteristics of composites (saturation magnetization, Bloch constant, local anisotropy field, ferro-magnetic resonance line width, coercive force) are studied. The phase compositions of initial composite particles and compacts prepared by two methods (DC and CP) are determined from the anisotropy field and the Bloch constant values using magnetic phase analysis. It is shown that the use of composite particles in dynamic compaction allows obtaining homogeneous nanostructured bulk materials while preserving magnetic characteristics of initial powders.
