Magnetic properties of nanostructured SiOo2:Eu3+ powders

Effect of fuel content on structural and magnetic properties of solution combusted Mn0.8Zn0.2Fe2O4 powders

Single phase Mn0.8Zn0.2Fe2O4 powders were synthesized by solution combustion method. The solution combustion method relies on the exothermic self-sustained reactions in reactive solution containing of oxidizers and organic fuels. In this work, the effects of various amounts of glycine as fuel on the powder characteristics were investigated. The structure, cation distribution, microstructure, ma...

Magnetic Properties of Nanostructured CoPt and FePt Thin Films

Polycrystalline MgO underlayer films lead to different preferred orientations of 10 CoPt and FePt films after the annealing process, depending on the thickness of 10 films. 10 films with a thickness greater than 20 nm revealed mostly 10 [100] fiber texture and consequently in-plane anisotropy as determined by magnetic hysteresis. Strong perpendicular anisotropy due to the 10 [001] fiber texture...

Spin Transport Properties of Manganese Doped Nanostructured Magnetic Semiconductors

Bulk Properties of Powders

THE P/M INDUSTRY has grown considerably in the past decade. As a result of this growth, more critical components in the automotive, aircraft, tooling, and industrial equipment industries are being considered for manufacture using this technology: This is placing increasingly stringent quality requirements on the final P/M part. Variations in part density, mechanical properties including strengt...

Spark-plasma-sintering (SPS) of nanostructured titanium carbonitride powders

Spark-Plasma-Sintering (SPS) compaction experiments of nanostructured titanium carbonitride powders have been performed at 1600°C and 1800°C (sintering time = 1 min). The as-received nanostructured samples have been synthesized by rapid condensation from the gas-phase (high frequency plasma). The sintering results were compared with data obtained by various conventional sintering techniques suc...
