Magnetic properties of NdFeTiB alloys with NdFe11Ti and/or Nd2Fe14B phases

The temperature relationship of the fluctuation field and coercivity in NdFeB alloys Coercivity of Ti-modified nanocrystalline (cu-Fe)-NdaFelaB alloys with soft iron particles embedded in hard Nd2Fe1,B matrix was studied. The alloys were prepared by melt spinning and annealing. The grain size of Nd,Fe,,B is from 20 to 60 run, while that of the soft iron particles is 11 to 30 nm. The coercivity of the annealed flakes decreased dramatically with increasing particle size of free iron, following the same tendency of a theoretical calculation by Schrefl et al. For the Ti-alloyed flakes, the 1 at. % Ti-containing ones show the highest coercivity of 11.1 kOe. Its (BH), value is about 16 MGOe despite lower Nd and B contents than stoichiometric Nd,Fer,B. More Ti addition would deteriorate the coercivity. 7072
