  Transparent lyotropic ferronematic dispersions are synthesized by admixing a
cationic ferrofluid to the lyotropic liquid crystal PL/1D/Wt. The transparency
is spontaneous and time-independent. It is observed in zero magnetic field in
white and polarized light for disordered layers of ferroliquid crystals of
thicknesses ~1 cm in both isotropic and nematic phases. Justification of the
low extinction of light in the systems of the lyotropic origin is presented.
