Magnetic excitations in CuCrO2, CuCr0.97Mg0.03O2, Cu0.85Ag0.15CrO2, and CuCr0.85Al0.15O2 have been studied by powder inelastic neutron scattering to elucidate the element substitution effects on the spin dynamics in the Heisenberg triangular-lattice antiferromagnet CuCrO2. The magnetic excitations in CuCr0.97Mg0.03O2 consist of a dispersive component and a flat component. Though this feature is apparently similar to CuCrO2, the energy structure of the excitation spectrum shows some difference from that in CuCrO2. On the other hand, in Cu0.85Ag0.15CrO2 and CuCr0.85Al0.15O2 the flat components are much reduced, the low-energy parts of the excitation spectra become intense, and additional low-energy diffusive spin fluctuations are induced. We argued the origins of these changes in the magnetic excitations are ascribed to effects of the doped holes or change of the dimensionality in the magnetic correlations.
