- 論文の詳細を見る
The magnetic properties of Y_2(Co_<1-x>T_x)_<14>B(T=Mn, Fe, Ni) are studied by means of NMR and magnetic measurements. The substitution of Fe and Mn for Co in Y_2Co_<14>B affects the magnetic anisotropy with a spin reorientation from plane to axis. The relationships between the anisotropy changes and the hyperfine fields of ^<59>Co nuclei determined by NMR are studied. The evaluated Co orbital moments and the increases of the hyperfine fields at 8j_1 and 8j_2 sites are larger than those at other sites, so Co at 8j_1 and 8j_2 sites give the large contribution to the anisotropy of the 3d sublatice. These anisotropy changes are interpretted by the estimated local anisotropy energy per atom, Es, at each site and the preferential substitution of Fe and Mn for Co at 8j_2 site.
