  We prove that for a hard core interaction the ground state spin polarization
in the low Zeeman energy limit is given by $P=2/\nu-5$ for filling fractions in
the range $ 1/3 \leq\nu\leq 2/5 $. The same result holds for a Coulomb
potential except for marginally small magnetic fields. At the magnetic fields
$B<20T$ unpolarized quasielectrons can manifest themselves by a characteristic
peak in the I-V characteristics for tunneling between two $\nu=1/3$
ferromagnets.
