Synthesis, Characterization and Investigation of Magnetic Properties of Co3O4/CoFe2O4 Nanocomposite Prepared by Calcination of [CO(SALEN)(PPH3)(H2O)]4[Fe(CN)6] and [Co(Salophen)(PPH3)(H2O)]4[Fe(CN)6] Binary Complex Salts
In this research the synthesis of [Co(Salen)(PPh3)(H2O)]4[Fe(CN)6] and [Co(Salophen)(PPh3)(H2O)]4[Fe(CN)6] schiff base complexes was reported. Co3O4/CoFe2O4 magnetic nanoparticles were prepared by calcination of these complexes at 500, 550 and 600°C. Precursor complexes were identified by FT-IR and UV-Vis spectroscopy and their thermal behavior was studied via TG/DTA. Nanomagnetic samples were ...
متن کامل(M=Cr,Mn,Fe,Co) by LSDA and LSDA+U
We have implemented a systematic LSDA and LSDA+U study of the double perovskites A2FeReO6 (A=Ba,Sr,Ca) and Sr2MMoO6 (M=Cr,Mn,Fe,Co) for understanding of their intriguing electronic and magnetic properties. The results suggest a ferrimagnetic (FiM) and half-metallic (HM) state of A2FeReO6 (A=Ba,Sr) due to a pdd-π coupling between the down-spin Re5+/Fe3+ t2g orbitals via the intermediate O 2pπ on...

Investigation of Tribological Behavior of Electrodeposited Cr, Co-Cr and Co-Cr/TiO2 Nano-Composite Coatings
Electrodeposition is a simple and economic technique for precision coating of different shaped substrates with pure metal, alloy or composite films. Dc electrodeposition was used to produce Cr, Co-Cr and Co-Cr/TiO2 nano-composite coatings from Cr(III) based electrolytes onto 316L SS substrates. The effects of TiO2 nanoparticles concentration on co-deposition of these particles along with Cr con...
متن کاملCavitation erosion of laser processed Fe-Cr-Mn and Fe-Cr-Co alloys
Purpose: Purpose of this paper is attempt explanation how laser beam processing influence on the cavitation performance of the Fe-Cr-Mn and Fe-Cr-Co alloys. This kind of alloys are frequently used in Polish power plants to routine repairs of damaged blades working under cavitation loading. Design/methodology/approach: Padding welds of investigated alloys were tested for three cases: after laser...
