TEM image, EDX spectra, XRD pattern, and HRTEM of CoFe2O4 nanocrystals. Low magnification TEM image (a) of CoFe2O4 nanocrystals synthesized via a solvothermal process and its corresponding EDX spectra (b). (c) XRD patterns of the CoFe2O4 nanocrystals reacted for 10 and 20 h. (d) High-resolution TEM image. Inset, corresponding its fast Fourier transform indicating the particle is oriented along the zone axis .
