PROBLEM TO BE SOLVED: To provide a method for increasing the magnetic properties of hexagonal ferrite by the incorporation of additional oxide.SOLUTION: Provided is a Y phase hexagonal ferrite material, e.g., including strontium, and being an increased hexagonal ferrite material using an oxide having a stoichiometry consistent with that of SrCoFeO,SrFeOor CoFeO. The hexagonal ferrite being the one made of a single phase or two different phases.The hexagonal ferrite has a Q value higher by about 20 under 800 MHz, has a Q value higher by about 15 under 1 GHz, has a permittivity of 6 to 8 under 0.8 to 1 GHz, and has a dielectric constant satisfying the permittivity of about 10 to 11.SELECTED DRAWING: Figure 1 |
