The magnetic Fredericksz trannsition in ferronematics (thermotropic nematic liquid crystals 7CΒ and MBBA combined with fnie magnetic particles of a size 10 nm) as a function of concentration of magnetic particles was studied by using simple dielectric measurements. The increase of the threshold magnetic field is observed in 7CΒ based ferronematic while the decrease of threshold field in MBBA based ferronematic is observed when the concentration of magnetic particles is increased. Experimental results are discussed in the framework of Brochard, de Gennes and Burylov, Raikher theories. PACS numbers: 64.70.Md, 61.30.Gdread more

Magneto-optic effects in colloids of ferromagnetic nanoparticles in nematic liquid crystals
TL;DR: In this paper, the effect of the nanoparticles shape and functionality on the suspension stability and magneto-optic properties were studied and a numerical model was developed to simulate the experimental results of the magnetic-field-induced Frederiks transition in nematic and ferronematic cells.
