The Sr M-type hexaferrites (SrFe<sub>12</sub>O<sub>19</sub>) are one of the most widely used magnetic material due to their cost efficiency, strong uniaxial magnetic anisotropy along the c-axis, and excellent chemical stability. Recently, many studies have improved the intrinsic magnetic properties of M-type hexaferrites by substitution, such as saturation magnetization and crystalline anisotropy. Previous reports have been mainly focused on La<sup>3+</sup>substitution for the Sr<sup>2+</sup> site and CO<sup>2+</sup> substitution for the Fe<sup>3+</sup> sites of M-type hexaferrites. In addition, there is generally requires a non-stoichiometric of iron ratio between 10 and 12 on Ba M-type hexaferrites. While iron deficiency is known to be helpful for the grain growth and the structure formation of NiZn spinel ferrites. Particularly, SiO<SUB>2-</SUB>CaO is widely used by suppressing crystal growth and high sintering density through Liquid - Phase Sintering.
However, the effect of La-Co substitution and iron deficiency on magnetic properties of the Sr-La-Co M-type hexaferrites remains unexplored. In this study, therefore, we tried to investigate La-Co substituted Sr M-type hexaferrites Sr<sub>1-x</sub>La<sub>x</sub>Fe<sub>12-x</sub>Co<sub>x</sub>O<sub>19</sub>, (0 ≤ x ≤ 0.4) ... 전체 초록 보기
