Abstract
In this study, the electromagnetic (EM) wave absorption properties of a two-layered structure composed of La_0.7Sr_0.3MnO₃-epoxy (10 wt.%) (LSMO) and SrFe_9.5Co_1.25Ti_1.25O₁₉-epoxy (10 wt.%) (SFCTO), both exhibiting distinct high-frequency magnetic and dielectric properties, were investigated using a High Frequency Simulation Software (HFSS) simulation tool. LSMO had a high dielectric constant (ε'..... More

Abstract
Mn, Zn, Ni-substituted Z-type hexaferrites, Sr₃Co₂Fe₂₄O₄₁ (Sr₃Co₂Fe_24-xMn_xO₄₁, Sr₃Co_2-yZn_yFe₂₄O₄₁, Sr₃Co_1-zNi_zZnFe₂₄O₄₁), were prepared by sol-gel synthesis processes and their high-frequency magnetic, dielectric and electromagnetic (EM) wave absorption characteristics were investigated. Substituting Mn for Fe by x = 0.5 maintained the single-phase Z phase while shifting the μ' , μ″ spectra towards lower..... More
