- 論文の詳細を見る
Measurements of hyperfine field and quadrupole coupling of Co^<59> have been made on the intermetallic compound Co_2B. A large anisotropy in the hyperfine field is observed. The hyperfine fields along the local orthorhombic axes (x, y, and z) of the Co sites are -53.7 kOe, -83.1 kOe, and -123.6 kOe, respectively, where the z axis is the two-fold axis which lies along the tetragonal <110> direction. The electric field gradients, ∣q_<xx>∣, ∣q_<yy>∣, and ∣q_<zz>∣, charge distribution compatible with the observed electric field gradients suggests that the electronic states near the top of the band have a character of ψ=α(3z^2-r^2)+β(x^2-y^2).
