Melt-spun ribbons were produced from the Pr8Dy1Fe60Co7Mn6B14Zr1Ti3 base alloy at the surface velocity of the cooper wheel of 30 m/s. The studies showed amorphous structure of ribbons and their soft magnetic properties. X-ray diffraction was used to determine phase constitution of all obtained samples. Annealing of ribbons caused formation of nanocomposite structure, which was a result of coexistence of hard magnetic RE2(Fe,Co)14B and soft magnetic α -Fe phases. Basic magnetic properties such as: coercivity JHc, remanence Jr and maximum energy product (BH)max were determined from the measured hysteresis loops. The microstructure of selected specimens was observed by transmission electron microscopy technique.
