Abstract

PURPOSE:To stabilize the negative temperature coefficient of a magnetic material by a method wherein proper quantity of the prescribed additive is added to the magnetic material. CONSTITUTION:At least one kind of MnO of less than 2mol%, MgO of less than 4.75mol%, CoO of less than 0.25mol% is added to Fe2O3 of 40mol%, CuO of 8mol%, ZnO of 30mol%, and NiO of 22mol% to constitute the magnetic material. When this magnetic material having the negative temperature coefficient is combined with a material having a positive temperature coefficient and is used for a core for electronic tuner, the temperature coefficicent of capacitor can be controlled easily and effectively.
