Influence of U and Cu on the crystallization process and magnetic propertie
s of the amorphous Fe86Zr6U1CuxB6-x (x = 0; 1) after heat treatment were in
vestigated. Structural measurement techniques showed the different course o
f crystallization process for both alloy systems. The positive influence of
Cu on the crystallization of homogeneous nanocrystalline structure was obs
erved as well as on magnetic properties.
