Abstract
The magnetic Fredericksz transition in a ferronematic (thermotropic ne matic liquid crystal MBBA combined with fine magnetic particles of siz e 10 nm) has been studied as a function of the concentration of magnet ic particles by means of simple dielectric measurements. A decrease in the threshold field is observed when the magnetic particle concentrat ion is increased, contrary to the Burylov-Raikher theory of thermotrop ic ferronematics.
