“…In the case of attribution of P3 to the interaction in a chain independent of whether it corresponds to pairs of I1 or V type, the analysis shows that the anisotropy of exchange interaction between Co2+ ions in a chain is more complicated than is predicted by (5).…”

The EPR spectra of single Co2+ ions and Co2+-Co2+ pairs in CsMg,-,Co,Cl, (x = O.OOO1 to 0.04) in Xand Q-bands are investigated. One type of single Co2+ spectra and four types of additional spectra attributed to Co2+-Coz+ pairs coupled by weak spin-spin interaction are observed. Using computer simulation of EPR spectra the parameters of spin-spin interaction are determined. The observed EPR spectra and the expected pair Co2+-Co2+ interactions in CsMg, _,Co,Cl, are analysed. The exchange parameters for the nearest neighbour Coz+-Coz+ pairs in the ab-plane are estimated. Thenature of the exchange anisotropy is discussed.

“…The compounds CsCoCl 3 and CsCoBr 3 have been studied through a variety of experimental techniques such as neutron scattering [4,5,[10][11][12][13], ESR [14,15], NMR [16] and Raman scattering [3,17]. A large body of experimental data thus exists with which theoretical results can be compared.…”

We consider the S = 1 2 Ising-like, fully anisotropic Heisenberg antiferromagnetic Hamiltonian in one dimension and study the dynamics of domain-wall excitations using perturbation theory. It is shown that the domain walls can form bound states. The transverse correlation function S xx (q, ω) is calculated in first-order perturbation theory and the zone-centre lineshape is found to be asymmetric towards lower energy. A comparison of the results with earlier theories as well as experimental results on CsCoCl 3 and CsCoBr 3 is made.
