Figure 3.15: Amplitude of the 120 ◦ magnetic order measured in our best wavefunction
for the 108 site cluster (left scale, full triangles) and the ratio of the
polarization M F on the saturated polarization M sat in our best wavefunction
(right scale, full circles). We show also the absolute magnetization M SDW for the
spin-density wave wavefunction (left scale, see also Fig. 3.16).
