Crystal structure and magnetic properties of Zn doped Barium M-Hexaferrite

---

Synthesis of Zn doped barium M-Hexaferrite (BaFe12_xZnxO19) has been peformed by co- precipitation method. The purified iron sand from Tulungagung is used as a precursor of Fe3O4. Synthesis of Zn doped Barium M-Hexaferrite with Variations of x = 0.3, 0.5 and 0.7 has been calcined at temperatures of 10000C for 5 hours. Ion Zn2+ (with 0 = x = 0.7 wt %) does not change the crystal structure of Barium M-hexaferrite (BaM), but give a slight displacement of the peak position of the diffraction pattern. SEM figures showed that Zn doped Barium M-Hexaferrite have a hexagonal structure, similar to BaM structure. Doping of Zn has changed the magnetic properties of Barium M-Hexaferrit (BaM), from hard magnetic become soft magnetic. Barium M-Hexaferrit (BaM) has a value of Coercivity Field (Hc) and Remanence Magnetization(Mr) is 0.003734 T and 8.334 emu/g. At variation x=0.3, the Remanence Magnetization (Mr) reaches the highest value. At this point, a value of Coercivity Field (Hc) and Remanence Magnetization (Mr) is 0.0506 T and 14.782 emu/gram respectively.
