Annealing-induced crystallization of the Er2Fe13.8B alloy amorphized by irradiation

Popis výsledku v původním jazyce

To study the evolution of structural and magnetic states of irradiation_amorphized Er2Fe13.8B alloy during isothermal annealing at temperatures of 295?1025 K, magnetization measurements and neutron diffraction analysis have been performed. The annealingof the alloy leads to the crystallization of the Nd2Fe14B-type phase, its amount reaches about 84% of the sample volume, and Fe (16%). Neutron diffraction studies have shown that the alloy crystallizes in a temperature range of 590?638 K. Magnetic measurements indicate the increase in the spontaneous magnetization and coercive force as the annealing temperature increases above 800 K. The magnetization of the Er sublattice in the sample annealed at 993 K is lower than that of the crystalline sample before its amorphization. However, the magnetic anisotropy of the Er sublattice is unchanged, i.e., the easy axes remain oriented in the basal plane of the tetragonal lattice.
