Two samples of ferronematics based on 8CB liquid crystal with different vol
ume fractions of magnetic particles were prepared. The influence of magneti
c field on the electric Fredericksz transition was studied in these samples
using magneto-dielectric measurements. The Burylov-Raikher's theory was ap
plied for the used experimental arrangement. A qualitative comparison of ob
tained experimental data with this theory was made and a good agreement was
found. (C) 1999 Elsevier Science B.V. All rights reserved.
