    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 0.5 Fe 0.5 ) p Mg q Zn x Mn y Fe z O 3/2(y+z)+1 , wherein
    0.03 ≦ p ≦ p 0.25
    0.30 ≦ q ≦ g 0.60
    0.35 ≦ x ≦ 0.50
    0.03 ≦ y ≦ 0.18
    1.70 ≦ z ≦ 1.90
    y+z
    and,
    p+q+x = 1.00
    The said material exhibits extremely low power losses and a relatively high initial permeability.

    摘要: A boron-free hard magnetic material on the basis of neodymium, iron and carbon which comprises a hard magnetic, finely crystalline tetragonal phase having a grain size equal to or smaller than 0.2 µm, and which has the Nd₂Fe₁₄C structure. The material can be obtained by spraying a molten alloy onto a rapidly moving chill surface, while forming flakes having a thickness of 30 µm or less. The material thus obtained is subsequently annealed at a temperature between 685 and 730°C, such that the desired structure is formed.
