Study of the magnetic Fredericksz transition in ferronematics
TL;DR: The magnetic Fredericksz transition in a ferronematic (thermotropic nematic liquid crystal MBBA combined with fine magnetic particles of size 10 nm) has been studied as a function of the concentration of magnetic particles by means of simple dielectric measurements as mentioned in this paper.
Journal ArticleDOI
The structural transitions in ferronematics in combined electric and magnetic fields
Peter Kopčanský,I. Potočová,Milan Timko,Martina Koneracka,A. M. G. Jansen,Jan Jadżyn,Grzegorz Czechowski +6 more
TL;DR: In this paper, the electric Fredericksz transition in 8CB-based ferronematics exposed to strong magnetic field was studied both theoretically (by means of the Burylov and Raikher's theory) and experimentally (using capacity measurements).
Journal ArticleDOI
Anomalous Kerr effect relaxation in an alternating field.
Jean-Louis Déjardin,Jan Jadżyn +1 more
TL;DR: Perturbation theory is used to derive the complex harmonic components arising in Kerr effect relaxation for an assembly of nonelectrically interacting, polar, and polarizable symmetric-top molecules acted on by a strong dc bias electric field superimposed on a weak ac electric field.
Journal ArticleDOI
Singular Pretransitional Behavior of the Electric Field-Dependent Part of the Thermodynamic Quantities of Strongly Polar Mesogenic Liquids in the Isotropic Phase
TL;DR: In this article, a new interpretation of the pretransitional temperature behavior of the static dielectric permittivity and its derivative in terms of the basic thermodynamic quantities: the internal energy, the entropy, and the Helmholtz free energy is presented.
Journal ArticleDOI
Determination of the nonlinear dielectric increment in the Cole-Davidson model.
Jean-Louis Déjardin,Jan Jadżyn +1 more
TL;DR: The problem of the nonlinear dielectric relaxation of complex liquids is tackled in the context of the Cole-Davidson model by using an appropriate time derivative of noninteger order, and an infinite hierarchy of differential-recurrence relations for the moments is obtained.
