MnMgCuZn ferrite material and the use thereof

摘要

There is disclosed an MnMgCuZn ferrite material which contains ranges of 46.5 to 50.4 mol% of iron oxide, 10.5 to 22.0 mol% of magnesium oxide, 22.5 to 25.0 mol% of zinc oxide, 6.0 to 16.0 mol% of copper oxide, and 0.1 to 3.5 mol% of manganese oxide. Advantages of an MnMgCuZn ferrite material that resistivity is relatively high and material cost is low are utilized to realize a superior MnMgCuZn ferrite material which is much smaller in magnetic loss than conventional materials of the same series and which has a sufficient saturated magnetic flux density. The use of this material in a deflection yoke core or a transformer for a high speed scanning cathode-ray tube is also disclosed.
