摘要：
We investigate the transition from the spin-singlet to the polarized incompressible ground state in systems with filling factor 2/3 using exact diagonalization with eight electrons. Directly at the transition the ground state is a new stable half-polarized state which seems to be gapless. This state reacts strongly to magnetic inhomogeneities but it prefers stripe-like spin structures to formation of domains.
