The competition between quantum and classical magnetization plateaus of S = 1/2 frustrated Heisenberg chains with modified exchange couplings is investigated. The conventional S = 1/2 frustrated Heisenberg chain is known to exhibit a 3-fold degenerate ↑↓↑ -type classical plateau at 1/3 of the saturation magnetization accompanied by the spontaneous ...

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...
