  • Abstract
    Annealing studies of initially amorphous TbFe2show a large increase in the coercive force at the onset of recrystallization. The coercivity increases from ≈100 Oe in the amorphous state to 3.75 kOe after a 525°C anneal. Neutron diffraction establishes the crystallite size as 100 A ±10A after a 415°C anneal and 150 A ±10A after a 525°C anneal. Following the 525°C anneal this material exhibited an energy product of 8.7 MGO (1 MGO = 106ergs/cm3) indicating considerable promise for recrystallized RFe2materials in permanent magnet applications.
