“…The spin wave excitation spectrum around the pure Ising energy consists of a continuum of states, accompanied by the propagation of domain wall pairs of the soliton response. The existence of a band of spin wave states and the soliton response have been confirmed within the quasi-one-dimensional system, CsCoM 3 (M=Br, Cl), by Satija et al [2] and Nagler et al [3].…”

“…The plots are clearly asymmetric towards the lower energies. In figure 5, the dispersion of the peak positions of S xx (q, ω) for various values of q are shown and compared with the experimental results (open circles) of Satija et al [10].…”

“…is the Green function defined with ( 9) and (10). G (i,j ) can be evaluated by techniques similar to those used for the evaluation of Green functions in the NN tight-binding model with free ends [2].…”

“…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.…”
