In order to investigate the phase constitution of the nanocrystalline Nd9.5Fe63.65B21.85Nb5 alloy ribbons in the as-cast state and after short-time annealing Mossbauer study has been carried out. In as-cast state, ribbon samples were not fully amorphous but revealed soft magnetic properties. X-ray diffraction analysis showed the presence of hard magnetic Nd2Fe14B, metastable Nd2Fe23B3 and paramagnetic Nd1+epsilonFe4B4 phases in annealed samples. Mossbauer spectroscopy was used to determine the fractions of constituent phases formed during annealing of ribbons. Magnetic measurements were made with a vibrating sample magnetometer (VSM) and have shown that with increasing annealing temperature the remanence polarization Jr and maximum energy product (BH)max values were increasing.
