| Research Abstract |
Synthesis of Sr_3Co_2Fe_24O_41 Z-type and Sr_4Co_2Fe_36O_60 U-type hexaferrites with substitution of various divalent ions by polymerizable complex method was investigated. Single-phase of Zn-substituted Sr3Co2Z and Sr4Co2U hexaferrites were synthesized with various Zn content. Magnetic properties of obtained hexaferrites were evaluated. Temperature dependence of Zn-substituted Sr_3Co_2Z and Sr_4Co_2U hexaferrites suggests the possibility of their Magneto-Electric effect at room temperature. Magnetocrystalline anisotropy of the hexaferrites was weakened by Zn-substitution.
