The ground state phase transitions in the distorted S = 1 kagom´e Heisenberg antiferromagnet (KHAF) with single-site anisotropy D are studied by the numerical exact diagonalization method. For strong easy plane anisotropy, the hexgonal singlet solid (HSS) ground state of the uniform KHAF is destroyed and large-D state is realized. The quantum phase...

The magnetization process of the S = 1 and 1/2 kagom´e Heisenberg antiferromagnet is studied by means of the numerical exact diagonalization method. It is found that the magnetization curve at zero temperature has a plateau at 1/3 of the full magnetization. In the presence of √3 × √3 lattice distortion, this plateau is enhanced and eventually the f...
