How free are Composite Fermions at $ν = 1/2$ ? A NMR investigation

N. Freytag, M. Horvatić, C. Berthier +2

NMR measurements of the electron spin polarization have been performed on a 2D electron system at and around half-filled lowest Landau level. Comparing the magnetic field and the t…

Observation of a new phase transition between fully and partially polarized quantum Hall states with charge and spin gaps at $ν = 2/3$

N. Freytag, Y. Tokunaga, M. Horvatic +3

The average electron spin-polarization $P$ of two-dimensional electron gas confined in $GaAs/GaAlAs$ multiple quantum-wells was measured by nuclear magnetic resonance (NMR…

NMR Determination of 2D Electron Spin Polarization at $ν = 1/2$

S. Melinte, N. Freytag, M. Horvatic +4

Using a `standard' NMR spin-echo technique we determined the spin polarization of two-dimensional electrons, confined to GaAs quantum wells, from the hyperfine shift of Ga nuclei i…
