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 (Li0.5Fe0.5)pMgqZnxMnyFezO3/2(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 < 2.0 and, p+q+x = 1.00 The said material exhibits extremely low power losses and a relatively high initial permeability.
