Magneto-Optic Faraday Effect of Magnetic Fluids Based on MFe2O4 (M = Fe, Ni, Co) Particles
A study is performed of the magneto-optical Faraday effect of magnetic fluids based on MFe2O4 particles (M = Fe, Ni, Co) in which sodium oleate is used as dense surfactant. This allows Faraday rotation to be obtained at a low volume concentrations of these particles (0.25–0.5%). Rotation depends linearly on the strength of the magnetic field (500–1000 G), which is unsaturated up to 4000 G. The maximum effect is achieved for magnetic fluids based on CoFe2O4.
期刊介绍：
Bulletin of the Russian Academy of Sciences: Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It presents full-text articles (regular, letters to the editor, reviews) with the most recent results in miscellaneous fields of physics and astronomy: nuclear physics, cosmic rays, condensed matter physics, plasma physics, optics and photonics, nanotechnologies, solar and astrophysics, physical applications in material sciences, life sciences, etc. Bulletin of the Russian Academy of Sciences: Physics focuses on the most relevant multidisciplinary topics in natural sciences, both fundamental and applied. Manuscripts can be submitted in Russian and English languages and are subject to peer review. Accepted articles are usually combined in thematic issues on certain topics according to the journal editorial policy. Authors featured in the journal represent renowned scientific laboratories and institutes from different countries, including large international collaborations. There are globally recognized researchers among the authors: Nobel laureates and recipients of other awards, and members of national academies of sciences and international scientific societies.
