摘要: Abstract We have studied the demagnetization behavior for melt-spun nanocomposite Pr 8 Fe 87 B 5 ribbons in this paper. defined H ex which reflects magnetic hardening of α-Fe and irr expresses irreversible reversal hard phase. It is found that magnetization can be well described using . A single-phase observed as approximately equals to Remanence enhancement not only determined by intergrain exchange coupling but also dominated anisotropy 2 14 To achieve a high energy product (BH) max , ideal microstructure discussed. The mainly controlled inhomogeneous pinning nucleated type.
