Magnetic and Structural Properties of Rapidly Quenched Tetragonal Mn Ga Nanostructures

Nanostructured Mn Ga ribbons with and 1.1 were prepared using arc-melting, melt-spinning and annealing. As-spun samples crystallized into hexagonal and cubic Heusler crystal structures based on the concentration of Mn in Mn Ga. Upon vacuum-annealing the samples at 450 C for about 50 hours, both the hexagonal and cubic structures transformed into a tetragonal structure. High-temperature x-ray di...

Structural, magnetic and dielectric properties of pure and Dy-doped Co3O4 nanostructures for the electrochemical evolution of oxygen in alkaline media

In this study, spinel-type cobalt oxide (Co3O4) and Co3-xDyxO4 (x = 0.04 and 0.05 molar ratio) nanoparticles were synthesized via combustion method at 700 °C. Crystallite nature, phase purity and thermal analysis of the prepared compounds were investigated by PXRD, FT-IR and TGA techniques. Structural analyses were performed by the FullProf program employing profile matching with constant scale...

Effect of Annealing Temperature on the Structural, Magnetic and Optical Properties of SrCo2Fe16O27 Hexaferrite Nanostructure

In this paper, W-type SrCo2Fe16O27 hexaferrite nanostructures were synthesized by sol-gel auto-combustion method. Effect of annealing temperature on the structural, magnetic and optical properties of these SrCo2Fe16O27 nanostructures was investigated. In order to determine the annealing temperature of samples, the prepared gel was examined by thermo-gravimetric and differential-thermal analyses...

Synthesis of Magnesium Ferrite-Silver Nanostructures and Investigation of its Photo-catalyst and Magnetic Properties

In this research we first synthesized MgFe2O4 nanostructures via hydrothermal method using (Mg(NO₃)₂.6H₂O) and (Fe(NO₃)₃.9H₂O). The influence of concentration, surfactant, precipitating agent and temperature on the particle size and magnetic properties of the synthesised nanoparticles were examined. Then MgFe2O4-Ag nanocomposites were prepared by a simple chemical precipitation. The structural ...
