Magnetic excitations in CuCrO $_{2}$ , CuCr $_{0.97}$ Mg $_{0.03}$ O $_{2}$ , Cu $_{0.85}$ Ag $_{0.15}$ CrO $_{2}$ , and CuCr $_{0.85}$ Al $_{0.15}$ O $_{2}$ have been studied by powder inelastic neutron scattering to elucidate the element substitution effects on spin dynamics in the Heisenberg triangular-lattice antiferromagnet CuCrO $_{2}$ . We found a variety of changes in the magnetic excitation spectra caused by the different types of the element substitutions. We argued that the origins of these changes in the magnetic excitations are the effects of doped holes or the change in dimensionality in magnetic correlations.
