摘要：

The recoil behavior of melt-spun ribbons of Zr-doped alpha-Fe/Nd2Fe14B alloys has been investigated by analyzing hysteresis curves and recoil loops of demagnetization curves. A drastic increase of the coercivity H-c from 620kA/m to 855kA/m at room temperature by an addition of 1 at.% Zr in alpha-FeiNd(2)Fe(14)B alloys has been observed. According to integrated recoil loop area, it is found that the maximum value of the integrated recoil area for Zr-doped sample (3.05 kJ/m(3)) is significantly lower (about 7 times) than that value for the Zr-free sample (20.9 kJ/m(3)). The reason of reduced recoil loop area in high coercivity alpha-Fe/Nd2Fe14B nanocomposite alloys by Zr addition was discussed in term of the process of irreversible magnetization reversal also.
