Abstract :
In the present research, rapidly solidied Fe85.3B11P3Cu0.7 ribbons were prepared by melt spinning process.
The microstructural variation, as well as magnetic properties of the as-spun and annealed ribbons, were characterized
by X-ray diffraction (XRD), transmission Mossbauer spectroscopy and alternating gradient eld magnetometer
(AGFM). The results showed two separated distinct exothermic peaks during heating, resulting from the phase transition
from amorphous to -Fe and then to Fe3B, respectively. The study of magnetic properties in the amorphous and
nanocrystalline states revealed that annealing the amorphous ribbons at 440˚C for 10 minutes gives rise to a signicant
increase in saturation magnetization (220 emu/g) which makes this alloy a good candidate for power applications.
