摘要

M-type barium hexaferrites doped with Sm³⁺, Ba_1-xSm_xFe₁₂O₁₉ (x=0.00, 0.05, 0.10, 0.15, 0.20, 0.30, 0.50) were prepared by conventional solid state reaction technique. Occupation of Sm³⁺ ions in Ba_1-xSm_xFe₁₂O₁₉ was investigated by X-ray diffraction, X-ray absorption fine structure and X-ray photoelectron spectrum. The changes of crystal cell volume and valency of Sm, Ba and Fe ions indicated that Sm³⁺ occupied Ba²⁺ sites and Fe³⁺ ions were partially reduced to Fe²⁺ ions to keep the valence neutrality.
