摘要：
The uniaxial anisotropy of Tb19Co81 and Tb19Fe81 amorphous alloy films was investigated by using X-ray diffraction analysis and measuring the magnetic anisotropy constants, K(u), on annealing at 200-degrees-C. It was revealed that, in the Tb-Fe film investigated, the anisotropic structure was more extensively relaxed at an early stage of annealing than in the Tb-Co film. During this relaxation process, near-neighbor correlations changed mainly around Tb-Tb pairs in the Tb-Fe film, whereas they changed mainly around Co-Co pairs in the Tb-Co film. The magnetic anisotropy decreased more rapidly in the Tb-Fe film than in the Tb-Co film, reflecting this difference in the structural relaxation process.
