Abstract

Magnetic Fréedericksz transition was studied in ferronematics based on the nematic liquid crystal 4-(trans-4'-n-hexylcyclohexyl)-isothiocyanatobenzene (6CHBT). 6CHBT was doped with rod-like magnetic particles of different size and volume concentration. The volume concentrations of magnetic particles in the prepared ferronematics were φ{symbol}1=10-4 and φ{symbol}2=10-3. Structural changes were observed by capacitance measurements, which evidenced of a significant influence of the concentration, shape anisotropy and/or the size of the magnetic particles on the magnetic response of these ferronematics.
