| 英文摘要 | The nanocrystalline ribbons with nominal compositions of PrCo6.6Ti0.4Bx (x = 0-0.35) were prepared by melt-spun technique, and the phase structure, the magnetic properties, and magnetization behaviors have been investigated. The XRD patterns show that the main phase of ribbons is the 1:7 phase, and the visible diffraction peaks of PrCo4B phase appear when the B content is larger than 0.2. The coercivity initially increases with increasing B content, reaching a maximum value of 5.2 kOe at x = 0.2, and then decreases slightly. The reversible magnetization m(rev)(H) increases monotonously with the increase of external field for the ribbons without B. But the maxima of m(rev)(H) are obtained in the vicinity of H-ci for B-containing ribbons, which is similar to that found in nanocomposite magnet. It may be due to the presence of PrCo4B magnetic phase with a softer magnetocrystalline anisotropy. According to the Henkel-plot analysis, the intergrain exchange coupling is enhanced with increasing B content. The analysis of the field dependence of coercivity suggests that the magnetization reversal mechanism is mainly controlled by inhomogeneous domain wall pinning.
