The spin polarization of 2D electrons in the region 1 < v < 2 and a determination of the Composite Fermion mass
PHYSICA E 12:1-4 (2002) 93-96
Abstract:
We report a study of the spin polarization of the Composite Fermion system in the occupancy range 1 < v(e) < 2 equivalent to the occupancy range 1 > v(h) > 0 of Composite Fermion holes, Polarized magneto-reflectivity is used to measure the polarization of the unoccupied states in the lowest Landau level. We observe the existence of spin polarized and unpolarized states at v(e) = 5/3 = 2 - 1/3 and v(e) = 4/3 = 2 - 2/3. We measure the polarization of the Composite Fermion gas at v(e) = 3/2 = 2 - 1/2 from which we can deduce the Composite Fermion mass. (C) 2002 Elsevier Science B.V.
