HIGH SATURATION MAGNETIZATION AND HIGH DIELECTRIC CONSTANT FERRITES
The disclosed technology relates to a ceramic composition and an article formed therefrom. A ceramic article for radio frequency applications is formed of a ceramic material having a chemical formula represented by: Bi1.0+aY2.0−a−x−2yCax+2yFe5−x−yMIVxVyO12 or Bi1.0+aY2.0−a−2yCa2yFe5−y−zVyInzO12. The ceramic material has a composition such that a normalized change in saturation magnetization (Δ4πMs), defined as Δ4πMs=[(4πMs at 20° C.)−(4πMs at 120° C.)]/(4πMs at 20° C.), is less than about 0.35.
