Biasing the ferronematic - a new way to detect weak magnetic field
Natalia Tomasovicova, Jozef Kovac, Yuriy Raikher +6
Magnetic properties of a ferronematic, i.e., nematic liquid crystal doped with magnetic nanoparticles in low volume concentration are studied, with the focus on the ac magnetic sus…
High concentration ferronematics in low magnetic fields
T. Tóth-Katona, P. Salamon, N. Éber +3
We investigated experimentally the magneto-optical and dielectric properties of magnetic-nanoparticle-doped nematic liquid crystals (ferronematics). Our studies focus on the effect…
Low magnetic field induced capacitance changes in ferronematics
Natália Tomašovičová, Milan Timko, Zuzana Mitróová +7
The response in capacitance to low external magnetic fields (up to 0.1 T) of suspensions of spherical magnetic nanoparticles, single-wall carbon nanotubes (SWCNT), SWCNT functional…
Laser-induced instabilities in liquid crystal cells with a photosensitive substrate
István Jánossy, Katalin Fodor-Csorba, Anikó Vajda +1
Liquid crystal layers sandwiched between a reference plate and a photosensitive substrate were investigated. We focused on the reverse geometry, where the cell was illuminated by a…
Temporal response to harmonic driving in electroconvection
Tibor Toth-Katona, Nandor Eber, Agnes Buka
The temporal evolution of the spatially periodic electroconvection (EC) patterns has been studied within the period of the driving ac voltage by monitoring the light intensity diff…
Flexoelectricity and competition of time scales in electroconvection
Tibor Toth-Katona, Nandor Eber, Agnes Buka +1
Novel behavior in electroconvection (EC) has been detected in nematic liquid crystals (NLCs) under the condition of comparable timescales of the director relaxation and the period…
