We report the synthesis of lyotropic ferronematics with a content of magnetic
nanoparticles (
) up to 1 vol.%. In the ferrodiscotic phase
we observe a magnetic Frederiks transition with critical fields about two
orders of magnitude lower than that for an undoped lyotropic system. A model
accounting for the magnetic polarization behavior of the studied ferronematics
is presented.
