dcterms:description
Magnetization and neutron diffraction measurements have been carried out to study evolution of structure and magnetic states of amorphous Nd2Fe14B and Er2Fe14B alloys under isothermal annealing at 295–1025 K. The amorphization have been performed by neutron irradiation which provides a homogeneous state in different with other methods of amorphization. The annealing induces a rise of alpha-Fe phase content in alloys and a recrystallization into Nd2Fe14B-type phase. Neutron diffraction data show that the recrystallization occurs over narrow temperature interval (590–638) K in the Er alloy and at around 800 K in the Nd alloy. Magnetic measurements testify that in both samples the magnetization and coercive field increase with annealing temperature above 800 K.
