Yb. Kim et al., Effects of powder alignment on determination error of spin reorientation angle of cone anisotropy, J MAGN MAGN, 195(3), 1999, pp. 741-744
The effects of powder alignment on the determination error of the spin reor
ientation angle (SRA) from polycrystalline magnetization curves have been e
xamined. A theoretical calculation showed that highly aligned powder is des
ired to determine the SRA with a high degree of accuracy. The effect of pow
der alignment on the SRA-error decreases when the SRA is increased. The SRA
of Nd2Fe14B determined from the magnetization measurements of magnetically
aligned powder coincided with the value reported on single crystals, and t
he determination error was evaluated to be within 1 degrees. (C) 1999 Elsev
