We report our results on temperature dependence of spin polarizations at ν=1 in the lowest as well as in the next higher Landau level that compare well with recent experimental results. At ν=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 ν=38 we predict that unlike the case of ν=32 the system remains fully spin polarized even at vanishingly small Zeeman energies.
