MONOCRYSTALLINE MATERIAL BASED ON BARIUM HEXAFERRITE Russian patent published in 1995 - IPC

Abstract SU 1693908 A1

FIELD: SHF equipment. SUBSTANCE: material has composition corresponding to crystalline chemical formula Ba₂Zn_2-x-yNi_xMn_yFe₁₂O₂₂, where x=0.2 + 0.35; y= 0.2-0.3. Invention results in generation of Curie temperature T_c=190-210 C; ΔH= 10.0-10.8 Oe. EFFECT: provision for increased Curie temperature and enhanced thermal stability of working frequency and expanded frequency range owing to it with maintenance of narrow width of curve of ferromagnetic resonance. 1 dwg, 1 tbl
