Dynamical magnetic properties of BaCoS 2 which has a layered structure and exhibits Mott metal-insulator (M-I) transition with the Ni-substitution for Co and/or with increasing external pressure p , have been studied by means of neutron inelastic scattering in the pressure range of \(0{}p{}15\) kbar. By comparing the results with those of BaCo 0.82 Ni 0.18 S 2 , we find that characteristics of the magnetic fluctuations near the two M-I transitions induced by pressure and by the Ni-substitution for Co are rather different, even when they are compared under the conditions of similar Néel temperatures and similar antiferromagnetic staggered moments at low temperatures.
