The aim of presented work was to study influence of preparing conditions on phase constitution and magnetic properties of the RE-Fe-B nanocomposite magnets doped with Zr. X-ray studies carried out for samples obtained under lower pressure of Ar atmosphere (0.6 × 105 Pa) revealed higher ability to formation of nanocrystalline structure. In case of higher pressure of Ar (0.8 × 105 Pa) it was possible to obtain full amorphous ribbon during melt-spinning process. The best magnetic properties (means the higher values of coercivity field JHc, remanence Jr and maximum energy product (BH)max) were measured for sample prepared with the lowest copper wheel speed 20 m/s and higher pressure of Ar (0.8 × 105 Pa).
