Abstract
Tunneling conductance G(T) through a constricted point contact is stud ied for the v=2/3 spin-singlet edges. Including spin-flip tunneling, Z eeman splitting, and random magnetic impurities, we discuss the variou s crossovers of G(T) as a function of the temperature T. The behavior of G(T) is found to be quite different for spin-singlet and spin-polar ized cases, and hence G(T) is expected to serve as an experimental pro be for the polarized-unpolarized transition at v=2/3.
