Abstract
We report the synthesis of lyotropic ferronematics with a content of m agnetic nanoparticles (similar to 6 nm) up to 1 vol.%. In the ferrodis cotic phase we observe a magnetic Frederiks transition with critical f ields about two orders of magnitude lower than that for an undoped lyo tropic system. A model accounting for the magnetic polarization behavi or of the studied ferronematics is presented.
