Effect of Ti substitution on the magnetic properties, microstructure, and aftereffect of melt spun PrFeB nanocomposites

The effect of Ti substitution on the magnetic properties, microstructure, and aftereffect of Pr x Fe 90− x B 10 ( x = 7–9.5) ribbons has been investigated. Thermal magnetic analysis and transmission electron microscopy reveal that 2 at.% Ti substitution effectively suppresses the 2:23:3 phase to for...

Summary:The effect of Ti substitution on the magnetic properties, microstructure, and aftereffect of Pr x Fe 90− x B 10 ( x = 7–9.5) ribbons has been investigated. Thermal magnetic analysis and transmission electron microscopy reveal that 2 at.% Ti substitution effectively suppresses the 2:23:3 phase to form a larger amount of Pr 2Fe 14B and α-Fe phases, and refines grain distribution. Accordingly, the improved magnetic properties with higher coercivity are obtained in Ti substituted series nanocomposites. The relationship of the activation volume and coercivity for PrFeB nanocomposite could be fitted as V ∼ i H c - 1.6 .
