Static magnetic properties and cation distribution in partially inverse polycrystalline Ni–Co ferrites

Mechanochemical synthesis and characterization of nanocrystalline Ni1-xCoxFe2O4 (0 ≤ x ≤ 1) ferrites

“…The inset shows the almost linear variation of saturation magnetization with heating temperature.Coercivity also shows a similar tendency with T, increasing about 50% between 600 and 800ºC. As shown in Table2, the obtained values of Ms and Hc for sample NCF-0.5-800 agree with those previously reported for Ni 0.5 Co 0.5 Fe 2 O 4 synthesized by other methods[28,[52][53][54][55][56][57]. It is important to remark that from the vast existing literature on this mixed ferrite, only reports dealing with materials with similar particle size and heating temperatures were selected for the comparison.…”
