ABSTRACT:
A low-loss oxide magnetic material consists of a Mn-Zn type ferrite which contains P, Al or Cr as well as SiO.sub.2 and CaO as sub-components. This magnetic material makes it possible to reduce the loss of electrical power under high-frequency or high-load conditions to a remarkable extent.
