Figure 4From: A novel method to fabricate CoFe2O4/SrFe12O19 composite ferrite nanofibers with enhanced exchange coupling effect TEM and HRTEM images and EDX spectrum of CoFe 2 O 4 /SrFe 12 O 19 nanofibers. TEM images (a, b), HRTEM image (c), and EDX spectrum (d) of CoFe2O4/SrFe12O19 nanofibers with a Co/Sr2+ molar ratio of 1.8. TEM image (e), top left inset in (e) showing a HRTEM pattern, and EDX spectrum (f) of CoFe2O4/SrFe12O19 nanofibers with a Co/Sr2+ molar ratio of 8.0.Back to article page
