    12±γ , where: -1 ≤ γ ≤ 1; 3(a+b+c+d+e+f) + 2(g+h+i) + 4(i+l) +5j = 24 ± 2γ; 1 ≤ a ≤ 3.5; 0 ≤ b ≤ 1.5; 0.1 ≤ c ≤ 1, preferably 0.65 ≤ c ≤ 1; 4 ≤ d ≤ 5; 0 ≤ e ≤ 1.5; 0 ≤ f ≤ 0.8; 0 ≤ g ≤ 1; 0.01 ≤ h ≤ 0.05; 0 ≤ i ≤ 0.2; 0 ≤ j ≤ 0.8; 0 ≤ k ≤ 0.5 and 0 ≤ I ≤ 0.5 and where TR is a rare earth preferably chosen from Gd, Dy, Ho or a mixture of rare earths. The invention also relates to processes for manufacturing such a ferrite and a microwave component including it, and to a microwave component thus obtained.
