The invention relates to a garnet-structured ferrite material having the following chemical formula: Y a TR b Bi b' Fe c Al d ln e Ca f Cu g Zr h V i Co j Si k O 12±γ , where TR is a rare earth or a combination of rare earths, TR not comprising Yttrium and ∘ -1 ≤ γ ≤1; ∘ 3 (a+b+b'+c+d+e) + 2 (f+g+j) + 4 (h+k) + 5i = 24±2 γ; ∘ 0 < a < 2; ∘ 0 ≤b ≤1; ∘ 1 < b' < 3; ∘ 3 ≤c ≤5; ∘ 0 ≤d ≤1.5; ∘ 0 ≤e ≤0.8; ∘ 0 < f ≤1; ∘ 0 < g ≤0.05; ∘ 0 ≤h ≤1; ∘ 0 ≤ i ≤ 0.8; ∘ 0 ≤ j ≤ 0.5; ∘ 0 ≤k ≤0.5. The invention also relates to a component and in particular a circulator incorporating the ferrite material of the invention. |
