Claim Text:
1. A magnetoelectric material which is a Y-type or Z-type hexaferrite material comprising: non-magnetic ions corresponding to aluminum (Al) ions or gallium (Ga) ions; metal ions including first ions and second ions, the first ions corresponding to barium (Ba), the second ions corresponding to at least one of strontium (Sr) ions, calcium (Ca) ions, scandium (Sc) ions, yttrium (Y) ions, gadolinium (Gd) ions, terbium (Tb) ions, dysprosium (Dy) ions, holmium (Ho) ions, erbium (Er) ions, thulium (Tm) ions, ytterbium (Yb) ions, and lutetium (Lu) ions; improvement ions increasing a resistance value and a degree of magnetic arrangement at a normal temperature, the improvement ions corresponding to at least one of manganese (Mn) ions, cobalt (Co) ions, nickel (Ni) ions, copper (Cu) ions, magnesium (Mg) ions, and zinc (Zn) ions; and magnetic ions interacting with each other and corresponding to iron (Fe) ions, wherein a distance between the magnetic ions is controlled by the non-magnetic ions or the metal ions.
