Abstract
Neutron profiles of spin waves in the Ising-type antiferromagnet CsCo were reexamined. Instead of well-defined magnon peaks, the spin-wave spectrum consists of a band of magnon states arising from the motion of domain-wall pairs. At the magnetic zone center, the energy of this band extends from to , whereas at the zone boundary a sharp resolution-limited peak at is observed.
