Effects of Gd³⁺-Substitution on the Structure and Magnetic Properties of Multi-Doped YIG Ferrites

Abstract:

Y₂_.₂₀_-xCa₀_.₈₀Gd_xV_0.₄₀In_0.₁₅Fe_4.₄₅O₁₂ garnet ferrite samples were prepared by solid-state reaction method, the effect of Gd-substitution on the microstructure and electromagnetic properties of YIG were systematically investigated. The results show that the substitution of Gd³⁺ makes the Ms~T curve more flat which improve the temperature stability of saturation magnetization; meanwhile, it appreciably increases the ferromagnetic resonance linewidth and spin wave linewidth.
