A series of Zr–Ni-substituted strontium hexaferrite materials, SrZr x Ni x Fe 12−2x O 19 (x=0.0–0.8), was synthesized by the co-precipitation method and the crystallite size determined to be in the range of 30–47nm. The saturation magnetization increased from 72 to 98kAm −1 while coercivity decreased from 1710 to 428Oe with Zr–Ni substitution. This improvement...
Strontium hexaferrite SrZr x Mn x Fe 12−2x O 19 (x=0.0–0.8) nanoparticles were synthesized by chemical co-precipitation and sol–gel combustion methods. The co-precipitation is found to be more suitable because samples synthesized by this method have a single phase for x=0.0–0.8 and DC resistivity is also improved by this method, whereas samples synthesized by the sol–gel...
