説明

The Co59 nuclear magnetic resonance in a bulk specimen of hexagonal cobalt has been observed as a function of temperature from 4.2 K to 730 K. The hyperfine fields at nuclei at the edge and center of the domain wall are determined to be 217.7 and 225.7 kOe at 4.2 K, respectively. The difference between the two hyperfine fields, 8.0±0.1 kOe, comes mainly from the anisotropy in the orbital field and partly from that in the dipolar field. The value of e2qQh−1 is 2.90±0.07 MHz at 4.2 K. The asymmetry in the charge distribution deduced from the electric field gradient q is very small. The isotropic hyperfine field is 223.0 kOe at 4.2 K and is larger by 8 kOe in its absolute value than that in cubic cobalt.
