We have examined the magnetic excitations in random magnetic and non-mannetic Isinx-like antiferromannets RbzCo.M:m .F4 with c=0.89 and c=0.70using neutron inelastic scattering techniques. The dynamic response functionsplits into four excitations throughout the Brillouin zone which are associatedwith the highly anisotropic Ising nature of Co ions. The intensity distributions atthe Brillouin zone boundary are in accord with the probability of local distribu-tions of magnetic neighbors of Co tons.
