Abstract

Inelastic neutron-scattering profiles of spin waves in the dilute quasi-one-dimensional Ising-like antiferromagnet CsCa_0.83Mg_0.17Br₃ have been investigated. Calculations of S^xx(Q,w), based on an effective spin Hamiltonian, accurately describe the experimental spin-wave spectrum of the 2J mode. The Q dependence of the energy of this spin-wave mode follows the analytical prediction w_xx(Q)=(2J)(1-5ε² cos² Qa+2ε²)^1/2, calculated by Ishimura and Shiba using perturbation theory.
