The present invention relates to an oxide magnetic material having high initial permeability and low loss characteristics suitable for use as a transformer core for communication equipment. 2. Description of the Related Art In recent years, electronic devices have become smaller, and electronic components used in electronic devices are also required to be smaller. In response to this demand, the present inventor engaged in the development of a high magnetic permeability and low loss inductance element, and came up with the present invention. In view of the above, the present invention provides an oxide magnetic material having high magnetic permeability and low loss characteristics. That is, the main components are ferric oxide (Fe 2 O 3 ), manganese oxide (MnO), and zinc oxide (ZnO), calcium oxide (CaO) 0.003-0.1% by weight, and bismuth oxide (Bi 2 O 3 ) 0.003-0.003% by weight. By adding 0.05% by weight and 0.003 to 0.1% by weight of vanadium oxide (V 2 O 5 ), an oxide magnetic material with high magnetic permeability and resistance loss is obtained. below. The present invention will be explained in detail with reference to the drawings. Figures 1 and 2 show a basic composition consisting of 52 mol% ferric oxide (Fe 2 O 3 ), 26 mol% manganese oxide (MnO), 22 mol% zinc oxide (ZnO), and calcium oxide (CaO). 0.003 to 0.1% by weight, bismuth oxide (Bi 2 O 3 ) 0.003 to 0.05% by weight, and vanadium oxide (V 2 O 5 ) 0.003 to 0.05% by weight were added singly or in combination, mixed, calcined, and then fired at 1300°C. Figure 1 shows the characteristic curve of the initial permeability μiac when CaO is
0.01wt%, and curves 1 to 5 are each V 2 O 5
0, 0.003, 0.01, 0.05 and 0.1wt%, and Figure 2 shows V 2 O 5 as 0.01wt% and curves 6 to 6.
Curve 10 has CaO of 0, 0.003, 0.01, and
0.05, 0.1wt% added. Moreover, FIG. 3 is a graph of the loss coefficient in the case of FIG. 1, and curves 11 to 15 indicate V 2 O 5 of 0, 0.003, and
0.01, 0.05 and 0.1wt% are added. FIG. 4 is a graph of the loss coefficient in the case of FIG.
0.01, 0.05, and 0.1wt% were added. From the drawing, it can be seen that the addition of calcium oxide or vanadium oxide alone does not improve μiac, but the combined addition with bismuth oxide significantly improves μiac in the range of 0.005 to 0.03 wt%. In addition, by adding CaO and Bi 2 O 3 together, CaO0.01
μiac in the range of ~0.03wt% Bi2O3 0.005 ~0.03wt%
The loss is significantly reduced without significantly reducing the In addition, by adding V 2 O 5 and Bi 2 O 5 together,
In the range of V 2 O 5 0.005 to 0.05 wt% and Bi 2 O 3 0.005 to 0.03 wt%, the loss becomes small without reducing the decrease in μica too much. CaO0.01 by combined addition of CaO, Bi 2 O 3 and V 2 O 5
~0.03wt%, Bi2O3 0.005 ~0.03wt%, V2O5 0.005
In the range of ~0.05wt%, the loss can be significantly reduced without significantly reducing μiac. Example Fe 2 O 3 52 mol%, MnO2 6 mol%, ZnO2 2 mol%
0.01 or 0.02% by weight of CaO in the basic composition consisting of
0.01% by weight of Bi 2 O 3 , 0.01 or 0.02% by weight of V 2 O 5
Add the composite, mix in a ball mill for 20 hours, and heat at 800℃.
After calcination for 2 hours, the outer diameter is 30φ, the inner diameter is 18φ, and the height is 10mm.
Formed into a ring-shaped sample and heated to 1.0% at 1300℃ for 4 hours.
Magnetic permeability (μiac) and magnetic loss coefficient (tan
δ/μiac) is shown in Table 1.
