Temperature dependence of spin polarizations at higher Landau Levels

Abstract

We report our results on temperature dependence of spin polarizations at $\nu =1$ in the lowest as well as in the next higher Landau level that compare well with recent experimental results. At $\nu =3$, except having a much smaller magnitude the behavior of spin polarization is not much influenced by higher Landau levels. In sharp contrast, for filling factor $\nu =\frac{8}{3}$ we predict that unlike the case of $\nu =\frac{2}{3}$ the system remains fully spin polarized even at vanishingly small Zeeman energies.
