SURVEY OF MAGNETIC-PROPERTIES DURING AND AFTER AMORPHOUS-NANOCRYSTALLINE TRANSFORMATION

In the first part of this paper, the metallurgical background of the a morphous-nanocrystalline transformation leading to the development of soft magnetic properties is discussed. The mechanisms of nucleation as well as grain growth hindering will be treated on the basis of metall urgical principles. The development of some technical magnetic propert ies during the nanocrystallization such as the loss characteristics an d the change in the domain structure will be compared. Finally, the de velopment of the field-induced anisotropy obtained during different he at treatments will be compared for the FINEMET-type and Fe-Zr based na nocrystalline alloys.
