Abstract

The temperature dependence of the spin-wave gap in the triangular antiferromagnet CsMnBr₃ was studied. The temperature dependence was studied using inelastic neutron scattering. The results showed that both grapped modes renormalized upwards with rising temperatures. A new magnetic anomaly was found in the paramagnetic phase.
