The effect of self-diffraction in magnetic fluids

Abstract The effect of optical self-diffraction occurs when an intensive interference field is created in a nonlinear optical medium. The aim of this work was to study the self-diffraction effect in magnetic fluids, i.e. generation of an optical grating by laser interference field due to the thermal diffusion phenomenon known as Soret effect. For the experiment we have used magnetic fluids with fine Fe 3 O 4 particles with various carrier base (water, kerosene, mineral oil). The proof of self-diffraction was evident from the observation of diffraction patterns. In our experiments we have observed the Soret effect with negative Soret constant.

The Structural Transitions in Liquid Crystals Doped with Fine Magnetic Particles

A review of envisaged future quark transversity measurements is presented.AbstractThe stable ferronematics and ferrosmectics (combination of liquid crystals with fine magnetic particles) were prepared for 8CB liquid crystal and magnetc particles 11 nm in diameter. The structural transitions i.e. magnetic Fredericksz transition were indicated by means of dielectric and conductivity measurements.The experimental results i.e. the proof of initial condition
