Abstract
Neutron diffraction and inelastic scattering studies have been carried out on a single crystal of BaCo0.82Ni0.18S2. Analyses of the form fac tor show that the system is in the high spin state. Two-dimensional na ture of the magnetic system has clearly been shown from the q-dependen ce of the magnetic excitations both above and below T-N. It is shown t hat a random phase treatment can roughly describe characteristics of t he magnetic excitations above T-N.
