Abstract

The spin unpolarised to spin polarised v=2/3 phase transition is studied in narrow quantum wells. The phase transition is mapped in the filling factor (ν), density (n)-plane and is well described assuming a Image dependence of the Composite Fermion effective mass. At high currents the huge longitudinal resistance anomaly appears along the phase boundary. A model is presented that treats the ...
