摘要: A series of the highly crystalline MFe2O4 ferrite spinel nanoparticles were synthesized via a modified Bradley reaction using microwave stimulation. Particle size was estimated theoretical calculations from X-ray data (Scherrer and Rietveld methods) as well by direct experimental techniques such TEM, DLS NTA. The calculated average grain for dry powders is in range 10 to 23 nm. Hydrodynamic measured on non-modified, surfactant free particles whole series. Raman spectra used additional verification structure features produced phases showed strong asymmetric behavior A1g mode, which deconvoluted revealing components. Among all products lowest site inversion found manganese (MnFe2O4). oxidation Fe3O4 leading formation Fe2O3 hematite phase induced laser irradiation observed. Magnetic characterization family carried out, showing that superparamagnetic blocking temperatures anisotropy constants K are good agreement with similar fine-particle systems.
