Emission Mossbauer spectroscopy study of the Fe3O4(100) surface and Fe3O4/MgO(100) and Fe3O4/CoO(100) interfaces

Physical Review. B: Condensed Matter and Materials Physics, 2003
Co-57 probe atoms were deposited on the surface of Fe3O4(100) films grown on MgO(100) substrates. In situ emission Mossbauer spectroscopy and reflection high-energy electron-diffraction measurements were performed on the surface after the deposition and after an annealing at 250 degreesC.

Controllable synthesis and magnetic properties of Fe3O4 and Fe3O4@SiO2 microspheres

Journal of Materials Science, 2010
We present a systematic study on the preparation, microstructure, and magnetic properties of Fe3O4 microspheres and Fe3O4@SiO2 microspheres. Results showed that Fe3O4 microspheres’ diameter can be tuned by Fe3+ concentration, whereas their average grain size can be tuned by polyethylene glycol (PEG) 2000 dosage or PEG molecular weight.

Synthesis and characterization of Fe3O4@ZnS and Fe3O4@Au@ZnS core–shell nanoparticles

Applied Surface Science, 2014
In the present work we report new assets on the synthesis and characterization of magnetite based core-shell nanoparticles such as Fe3O4@ZnS and Fe3O4@Au@ZnS. The composites were prepared by seed mediated growth which consist in a sequential growth of a second or third component on a preformed magnetite seeds in the presence of sodium laurylsulphate ...

2011
Solid solutions with spinel structure in the Fe3O4???Mn3O4???Co3O4 system were synthezed in the air. If Co3O4 exceeds 50 % mol. solutions split into 2 spinel phases. Parameters of elementary gate, magnetic moment and Kuri point were studied. It was found that relation enthalpy in forming spinel compounds and solid solutions to the total sum of enthalpy
