Magnetic Properties of Sr Substituted Co2Z Magnetoplumbite for Ultra High Frequency Uses.

XAFS study on site occupation of cobalt and iron in Z-type ferrite, Ba3Co2−xFe24+xO41

“…In order to improve the magnetic properties feasible for the UHF region, lot of studies have been carried out concerning the cation substitution and sintering conditions [2][3][4][5]. Only when Me ¼ Co in Ba 3 Me 2 Fe 24 O 41 , Z-type ferrite is magnetically soft material with its easy axis in the basal plane of the hexagonal structure [6].…”

Temperature Dependence of Magnetic Moment Orientation in Co2Z-Type Hexaferrite Estimated by High-Temperature Neutron Diffraction

“…[1][2][3][4][5] This material belongs to the family called ''ferroxplana'', in which the easy magnetization direction lies in the basal plane (c-plane) of the hexagonal structure. Magnetic moments of iron and cobalt ions in this material follow an alternating electromagnetic field even in the GHz region because a small anisotropic field rotates the moments around the c-axis and a relatively far larger anisotropic field turns them toward the c-axis.…”

“…Co 2 Z-type ferrite Ba 3 Co 2 Fe 24 O 41 with a hexagonal structure is regarded as a candidate for electromagnetic noise absorbent material in the GHz region, and many studies based on this suggestion have been carried out. [1][2][3][4][5] This material belongs to the family called ''ferroxplana'', in which the easy magnetization direction lies in the basal plane (c-plane) of the hexagonal structure.
