The influence of the order-disorder structural transition on the magnetic and magneto-optical properties of Fe-Al and Co-Al alloy filme has been investigated. The disordered states in the alliy films were prepared by vapour qoenching deposition on glass substarates cooled by liquid nitrogen. The experimental study of the magneto-opical properties of the ordered and disordered Fe0.52 Al0.48 and Co0.62 Al0.38 alloy films has been carried out in 1.05÷5.0 eV energy range at room temperature. The infuence of the order-disorder strucural transition on the magnetic and magneto-optical properties was discussed using the effective medium approximation and the strucural defect approach.

With the increasing demand for efficient and economic energy storage, tin disulfide (SnS2), as one of the most attractive anode candidates for the next generation high-energy rechargeable Li-ion battery, have been paid more and more attention because of its high theoretical energy density and cost effectiveness. In this study, a new, simple and effective process, mechanical alloying (MA), has been developed for preparing fine anode material tin disulfides, in which ammonium chloride (AC), referred to as process control agents (PCAs), were used to prevent excessive cold-welding and accelerate the synthesis rates to some extent. Meanwhile, in order to decrease the mean size of SnS2 powder particles and improve the contact areas between the active materials, wet milling process was also conducted with normal hexane (NH) as a solvent PCA. The prepared powders were both characterized by X-ray diffraction, Field emission-scanning electron microscopeand particle size analyzer. Finally, electrochemical measurements for Li/SnS2 cells were takenat room temperature, using a two-electrode cell assembled in an argon-filled glove box and the electrolyte of 1M LiPF6 in a mixture of ethylene carbonate(EC)/dimethylcarbonate (DMC)/ethylene methyl carbonate (EMC) (volume ratio of 1:1:1).
