Soft magnetic magnesium-manganese-zinc-ferrite material and products thereof

摘要

A novel MgMnZn-ferrite material is described which is particularly suitable for deflection rings which are mounted in the deflection coil of a cathode-ray tube. The material corresponds to the formula (Li_0.5Fe_0.5)_pMg_qZn_xMn_yFe_zO_3/2(y+z)+1, wherein0.03 ≦ p ≦ p 0.250.30 ≦ q ≦ g 0.600.35 ≦ x ≦ 0.500.03 ≦ y ≦ 0.181.70 ≦ z ≦ 1.90y+z 2.0and,p+q+x = 1.00The said material exhibits extremely low power losses and a relatively high initial permeability.
