抄録
The spin wave theory is developed on the basis of a triangular lattice Heisenberg antiferromagnet with a single-ion type anisotropy whose easy axis is perpendicular to the lattice plane (c-plane) in order to investigate the low-lying excited states of Néel-like 120° structure on a a-c plane. As a result of calculation only for electronic spins S as to k=0, a characteristic mode with quite a low energy is obtained. This mode corresponds to the swinging motion in the a-c plane, and reflects the present characteristic anisotropy and a frustration effect. In addition, the behavior of this mode under the influence of hyperfine coupling (−AS·I) with nuclear spins I is discussed. Consequently, the possibility of the abnormal NMR line whose energy is far less than that of normal NMR (AS) is pointed out. Further, the dispersion relation for various modes is discussed.
