| An effective-field theory based on the single-spin cluster has been used to study of a diluted spin-1/2 Ising antiferromagnet on the kagome lattice with nearest-neighbor interactions. We observe five plateaus in the magnetization curve of the diluted antiferromagnet when a magnetic field is applied which is in agreement with Monte Carlo calculation. The effect of the site-dilution on the magnetic susceptibility is also investigated and discussed. In particular, we have found that the frustrated kagome lattice inverse susceptibility falls to zero at 0 K. |
