Surface spin effects in La-doped CoFe2O4 nanoparticles prepared by microemulsion route

Popis výsledku v původním jazyce

A comparative study of pure CoFe2O4 nanoparticles and La-doped CoFe2O4 nanoparticles, prepared by microemulsion route has been performed. The samples were characterized using x-ray diffraction and transmission electron microscopy in order to obtain average particle size. preparation route. The samples were investigated by magnetization measurements, which revealed the coercivity values strongly dependent on particle size, but not significantly on level of La3ţ doping. Detailed in-field Mossbauer spectroscopy studies were performed in order to determine spin canting angles and cation distribution within the spinel network. The non-negligible canting angles up to 40_ in the La-doped samples were observed. The presence of the spin surface effects was alsosupported by magnetic measurement as the magnetization did not saturate even in considerably high magnetic fields (7 T).
