- Abstract
- B-11 pulsed NMR measurements have been performed to investigate local electronic structure and 4f spin dynamics for TbNi2B2C single crystal. B-11 NMR shift and linewidth are huge and strongly temperature dependent. In addition, both are proportional to magnetic susceptibility, indicating that the hyperfine field at the boron site originates from the 4f spins of Tb. The shift and the spin-lattice relaxation rate show high anisotropy for field parallel and perpendicular to the c-axis. Anisotropy of the shift and the relaxation rates suggests that the hyperfine field perpendicular to the c-axis is larger. (C) 2001 Elsevier Science B.V. All rights reserved.
