TL;DR: In this paper, a magnetic fluid based on cobalt ferrite nanoparticles was obtained using a hydrothermal treatment added to the Massart procedure, which increased the average size of the nanoparticles from 11.9 to 18.7 µm and also improved the dispersity and crystallinity of the cobalt-ferrite particles.

TL;DR: An experimental investigation on the origin of the magneto-optic effects of ferrofluids is presented in this paper, where the influence of two parameters, namely the magnetic anisotropy energy of particles and the carrier liquid viscosity, is studied.

TL;DR: In this paper, an extensive experimental work concerning measurement of longitudinal magneto-optic effects (Faraday rotation and circular dichroism) induced in magnetic liquids is presented, and seven ferrofluid samples allow the study of the influence of numerous parameters: magnetic suspension and carrier liquid characteristics, magnetic field strength (up to 10 kOe) and frequency (dc to 50 kHz), light wavelength (400 to 2000 nm) and temperature (253 to 373 K).

TL;DR: In this paper, a three dimensional magneto-photonic crystal was realized by a low temperature sol-gel method using self-assembled polystyrene direct opals, which were impregnated by CoFe2O4 nanoparticles doped with silica solgel solution.

TL;DR: In this article, the Brownian relaxation of three ferrofluids with Fe 2 CoO 4 particles dispersed in water, dibutyl phthalate and diethylene glycol is presented and compared with the theoretical model of Debye adapted to the magnetism.
