Magnetocrystalline Properties of Sr_1.4Ba_1.6Co₂Fe₂₄O₄₁

Abstract:

Multiferroic Ba_1.6Sr_1.4Co₂Fe₂₄O₄₁ with a Z-type hexagonal structure was obtained through the proteic sol-gel process with a single-phase, combined with thermal treatment at 1200 °C for 2 h. XRD analysis revealed the formation of a single phase, with preferential orientation in the case of a sample in pellet form. Magnetometry measurements revealed a low coercive field characteristic of Z-type hexaferrite, plus an electrical resistivity of approximately 2 × 10⁹ Ω.cm that was considerably higher than expected.
