Effect of Mn on the magnetic properties of Fe3B/Nd2Fe14B nanocomposites
Source abstract
Abstract
Abstract The magnetic properties of Nd 4.5 Fe 77− x Mn x B 18.5 ( x =0, 1 and 2) nanocomposites prepared by the crystallization of amorphous precursors were investigated. Addition of Mn is found to decrease the crystallization temperature of the amorphous ribbons. The intrinsic coercivity i H c and maximum energy product ( BH ) max increase from 2.6 kOe and 9.1 MGOe for x =0 to 3.1 kOe and 10.3 MGOe for x =1, respectively, and the remanence ratio M r / M s increases from 0.70 to 0.72. The effect of Mn on Curie temperature T C and the thermal stability of M r and i H c were also studied. 57 Fe Mossbauer spectra have been recorded for x =0, 1 and 2 ribbons at room temperature and site preference of the Mn atoms in Fe 3 B and Nd 2 Fe 14 B phases is discussed using the Mossbauer spectroscopy.
