Inelastic scattering of neutrons from random two-dimensional antiferromagnets Rb2Co sub(c)Mg sub(1-c)F4
Description
We have examined the magnetic excitations in random magnetic and non-magnetic Ising-like antiferromagnets Rb2Co sub(c)Mg sub(1-c)F4 with c = 0.89 and c = 0.70 using neutron inelastic scattering techniques. The dynamic response function splits into four excitations throughout the brillouin zone which are associated with the highly anisotropic Ising nature of Co ions. The intensity distributions at the Brillouin zone boundary are in accord with the probability of local distributions of magnetic neighbors of Co ions. (author)
