Phys. Rev. B 75, 155318 (2007) [5 pages]Spin phase diagram of the νe=4∕11 composite fermion liquidReceived 8 January 2007; revised 26 February 2007; published 13 April 2007 Spin polarization of the “second-generation” νe=4∕11 fractional quantum Hall state (corresponding to an incompressible liquid in a one-third-filled composite fermion Landau level) is studied by exact diagonalization. A spin phase diagram is determined for GaAs structures of different widths and electron concentrations. Transition between the polarized and partially unpolarized states with distinct composite fermion correlations is predicted for realistic parameters. © 2007 The American Physical Society URL:
