Screening of Mono-, Di- and Trivalent Cationic Dopants for the Enhancement of Thermal Behavior, Kinetics, Structural, Morphological, Surface and Magnetic Properties of CoFe₂O₄-SiO₂ Nanocomposites.

The d A and d B of the gels calcined at 700 and 1000 °C are higher for the doped CoFe 2 O 4 than the undoped CoFe 2 O 4 and display a decreasing trend for the monovalent dopant (Ag + , Na + ) ion and an increasing trend for the trivalent dopant (La 3+ ) ion ( Table 2 ).
