Metamagnetism in manganate magnesium ferrite

Magnesium Ferrite (MgFe2O4) Nanostructures Fabricated by Electrospinning

Magnesium ferrite (MgFe(2)O(4)) nanostructures were successfully fabricated by electrospinning method. X-ray diffraction, FT-IR, scanning electron microscopy, and transmission electron microscopy revealed that calcination of the as-spun MgFe(2)O(4)/poly(vinyl pyrrolidone) (PVP) composite nanofibers at 500-800 degrees C in air for 2 h resulted in well-developed spinel MgFe(2)O(4) nanostuctures. ...

Structural, magnetic, and magnetoelastic properties of magnesium substituted cobalt ferrite

Metamagnetism and Negative-Index Metamaterials

921 Abstract A new class of artificially structured materials called metamaterials makes it possible to achieve electromagnetic properties that do not exist in nature. In this article, we review the recent progress made in the area of optical metamaterials, specifically artificial magnetism and negative-index metamaterials. It was predicted that nanostructured metamaterials could provide magnet...

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 ...
