15 صفحه اولNanomanufacturing: Conversion of antiferromagnetic hematite (α-Fe2O3) nanocubes to ferrimagnetic spherical barium ferrite (BaFe12O19) nanoparticles
Recently, it has been shown that it is feasible to realize 29.5 Gb/in recording density employing hexagonal barium ferrite (H-BaFe) nanoplatelets [1]. Although H-BaFe nanoplatelets are a potential candidate for high density recording media, their greatest disadvantage is their dispersibility and agglomeration by forming poker-chip-like stacks due to mutual magnetic interactions [2-3]. To achiev...
متن کاملImproved Electrical Conductivity of CFRP by Conductive Silver Nano-particles Coating for Lightning Strike Protection
The improvement of electrical conductivity of carbon-fiber reinforced plastics (CFRP) has been investigated by conductive silver nano-particles coating for the purpose of aircraft lightning protection. Silver nano-particles in colloid were sprayed on the surface of carbon fibers, which were then impregnated by epoxy resin to form a CFRP specimen. Electrical resistance was measured by contact re...
متن کاملThe Effects of Hydrogen Reduction on Magnetic Properties of Barium Ferrite Particles
A reduction process of the substituted Ba-ferrite has been found to be devided into three steps. At the first and second steps, the magneto-plumbite structure maintains and the coercivity increases. When the reduced-substituted Ba-ferrite particles are reoxidized, the coercivity is reversible in the first step but irreversible in the second step. During the third step, the magneto-plumbite stru...
متن کاملEffects of Stoichiometry on the Magnetic and Structural Properties of Perpendicular Barium Ferrite Thin Film Media
The effects of stoichiometry factor on the magnetic and structural properties of perpendicular barium ferrite thin films with composition of BaO (Fe2O3) were systematically investigated. Within the range 2 2 6, the -axis for barium ferrite thin films can be oriented perpendicularly by the use of Pt underlayer and with optimized processing conditions. Perpendicular -axis orientation becomes wors...
