Temperature dependence of spin polarization at higher Landau levels

We report our results on the temperature dependence of spin polarizations at v = 1 in the lowest as well as in the next higher Landau level. They compare well with:recent experimental results. At v = 3, spin polarization has a smaller magnitude but is not much influenced by higher Landau levels. In sharp contrast, for filling factor v = 8/3 we predict that, unlike-in the case of v = 2/3, the system remains fully spin polarized even at vanishingly small Zeeman energies.
