Ni-Zn base ferrite

摘要

A Ni-Zn base ferrite is provided with a relatively small dielectric loss (tan delta ( epsilon )) of the order of 10<-3>. Its saturation magnetization (4 pi Ms) is relatively still high. A Ni-Zn base ferrite having a small dielectric loss (of the order of 10<-3>) can be obtained by proportioning raw materials to give a finished composition range of NiXZn1-XFe2-Y-ZMnYMZO4 where M: Ge and/or Sn, 0.55≤X≤1.00, 0.001≤Y≤0.36, and 0.002≤X≤0.36, by calcination.
