Abstract

The magnetic interactions in the nanocomposite Nd 2Fe,4B/α-Fe ribbons were investigated using δM measurements. In the melt spun ribbons both exchange and dipolar couplings are present whereas only the exchange coupling is observed to be present in the annealed ribbons. It is found from the present study that the removal of the grain boundary anisotropy on annealing strengthens the exchange coupling.
