Detailed analysis of the crystallization of the Co-P amorphous system: Kinetics, influence of magnetic order, and formation of textures

The crystallization kinetics of the amorphous Co-P system and the influence of the magnetic order of the samples on the microstructural and magnetic features of the crystallization product have been studied. By assuming an additive kinetics, the calculated temperature-time-transformation (T-T-T) and temperature-heating-rate-transformation (T-HR-T) curves are in good agreement with the experimental data. Scanning electron microscopy, x-ray diffraction, and magnetic measurements show that a dear texture is induced and that the easy axis of the amorphous samples is preserved during the crystallization process for samples with the Curie temperature well above the crystallization temperature. This clearly shows that magnetic order plays an important role in the crystallization in this system.
