Notes:
In this paper, several new main compositions are presented with Mn2+ substituted by Ti4+and Co2+ in Manganese-zinc ferrites in consideration of the strong influence of Ti4+ and Co2+ onthermal stability by different mechanisms. Moreover, the effects of these substitutions on suchparameters as permeability, electrical resistivity, density, and power loss are analyzed. Theexperimental results show that the proper substitution of Ti4+ or Co2+ in manganese-zinc ferrites canincrease the thermal stability remarkably. Furthermore, the effects of composition of Ti4+ andCo2+substitutions have interactive process, especially when Manganese-zinc ferrites with highthermal stability in 20°C~140°C are achieved when the substitution of Ti4+ is 0.10mol%and Co2+ is0.05mol%
