Preparation and magnetic properties of barium ferrites substituted with manganese, cobalt, and tin

►BaFe12−2xMnxSnxO19(x=0.2-1.0), BaFe12−2xCoxSnxO19 (x=0.2-0.8), and BaFe12−2xCox/2Mnx/2SnxO19 (x=0.1-0.6) have been prepared by a previously reported co-precipitation/molten salt method. ►Low coercivity temperature coefficients, which are adjustable by doping, were achieved by Mn-Sn and Mn-Co-Sn doping. ►Efficient synthesis and properties of barium ferrite and its derivatives are discussed in depth.
