Ruthenium doped Z-type hexaferrite
In an aspect, a ferrite composition comprises a Ru—Co2Z ferrite having the formula: (Ba3-xMx)Co2(M′Ru)yFe24-2y-zO41, wherein M is at least one of Sr, Pb, or Ca; M′ is at least one of Co, Zn, Mg, or Cu; x is 1 to 3; y is greater than 0 to 2; and z is −4 to 4. In another aspect, an article comprises the ferrite composition. In yet another aspect, method of making the ferrite composition comprises mixing ferrite precursor compounds comprising Fe, Ba, Co, and Ru; and sintering the ferrite precursor compounds in an oxygen atmosphere to form the Ru—Co2Z ferrite.
