さいことである。In general, +Ni-1drb-Zn based oxide magnetic materials are often used for high frequency applications. The properties required in this case are magnetic permeability, coercive force, etc. The characteristics required for materials for low-loss transformers include electrical resistance, key temperature, etc., but since they operate at high frequencies, in order to keep eddy current loss to a minimum, high electrical resistance is required. The crystal grain size is small in order to reduce transformer inertia in high frequency ranges.

下にする必要がある。As is clear from the examples in Table 1 and above, the oxide magnetic material of the present invention reduces loss by decreasing the crystal grain size and increasing the electrical resistance when C4゛α0 and V2O5 are not included, respectively. It can be reduced. Also,
If V2O5 is contained in excess of 0.25 wt%, the sinterability will deteriorate 1-2 and the loss will increase, so it is necessary to keep the content below 0.25 wt%.

Further, if C°αO-1 is contained in an amount of 0.5 wt% or more, the sinterability deteriorates and loss occurs, so it is necessary to limit the content to 0.5 wt% or less.
