FERRITE MATERIAL OF GRENATE TYPE WITH VERY LOW SATURATION MAGNET AND COMPONENT COMPRISING SAID MATERIAL WITH VERY LOW SATURATION MAGNETIZATION

摘要

One subject of the invention is a ferrite material of garnet structure with very low saturation magnetization characterized in that it corresponds to the following chemical formula: YaTRbBib'FecAldlneCafCugZrhViCOjSikO12±γ with TR: a rare earth or a combination of rare earths and: -1 ≤ γ ≤ 1; 3 (a+b+b'+c+d+e) + 2 (f+g+j) + 4 (h+k) + 5i = 24±2γ 1 ≤ a ≤ 3.5; 0 ≤ b ≤ 1.5; 0 b' ≤ 1; 4 ≤ c ≤ 5; 0 ≤ d ≤ 1.5; 0 ≤ e ≤ 0.8; 0 ≤ f ≤ 1; 0 g 0.05; 0 ≤ i ≤ 0.8; 0 ≤ j ≤ 0.5; 0 ≤ k ≤ 0.5; with b + d ≥ 1.2. Another subject of the invention is a component comprising said material of the invention and a magnetic ferrite material of garnet structure.
