“…The Faraday rotation as a function of wavelength at room temperature is measured using a precise equipment [4] based in transmission which allows us to obtained an accurary of 0.01°. A precedent study shown that the disappearance of the first order term I F by rotation of the analyzer gives the value of the Faraday rotation for a fixed magnetic field value [5].…”

PACS 78.20.Ls, 85.70.Sq Thin films of Yttrium Iron Garnet (YIG) are grown by radio frequency magnetron non reactive sputtering system on quartz and Gadolinium Gallium Garnet (GGG) for optical applications or alumina substrates for microwave applications. A post deposition annealing is needed to obtain the crystallization of YIG films and the magnetic properties which are correlated with the magneto-optical properties. Their crystallographic, morphologic and magnetic properties are explored. The variation of Faraday rotation is studied versus the wavelength. For both optical substrates, quartz and GGG, results are comparable with the literature for bulk material. A microwave isolator was realized with YIG thin film on alumina substrate in a coplanar configuration.

Inductive transducers with magnetic fluids (MF) for aerodynamic measurements have as essential components one or two pairs of identical electrical coils of circular cross section, uniformly wound. The carcasses of every pair of coils have the role of vertical cylindrical reservoir and communicate at the bottom creating a vertical U-shaped tube. At the equilibrium this tube is half filled with MF. The MF has the role of a magnetic liquid core. This U system measure a pressure difference in gases at the top ends of the carcasses, this one is proportional to the difference between the inductances of the coils. For these transducers the paper presents the mechanical functioning principle, the detailed correction solution for inclination and acceleration, a theoretical electronic measuring system having only one element for zero adjustment and also some technical characteristics of these transducers obtained by a numerical simulation method.

“…The uniform size and distribution of the crystals indicates extreme biological control of the mineralization process. Several magneto-optical effects on magnetic nanoparticles have been reported by several investigators [4][5][6][7]. Rosenblatt et al [5] described the birefringence technique, which was used to determine the average magnetic moments of magnetotactic bacteria in culture.…”
