How free are Composite Fermions at $\nu = 1/2$? A NMR investigation (2002)

Freytag, N., Horvatić, M., Berthier, C., Shayegan, M., Lévy, L. P.

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 temperature...

NMR investigation of how free composite fermions are at ν=1/2 (2002)

Freytag, N., Horvatić, M., Berthier, C., Shayegan, M., Lévy, L. P.

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

Observation of a new phase transition between fully and partially polarized quantum Hall states with charge and spin gaps at $\nu = 2/3$ (2001)

Freytag, N., Tokunaga, Y., Horvatic, M., Berthier, C., Shayegan, M., Levy, L.

The average electron spin-polarization $\cal P$ of two-dimensional electron gas confined in $\rm GaAs/GaAlAs$ multiple quantum-wells was measured by nuclear magnetic resonance (NMR) near the...

NMR Determination of 2D Electron Spin Polarization at $\nu=1/2$ (1999)

Melinte, S., Freytag, N., Horvatic, M., Berthier, C., Levy, L. P., Bayot, V., ...

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 in the wells....
