ORIENTATION OF THE MAGNETIC IONS IN MONOVALENT AND DIVALENT DOPED Sr-Zn W-TYPE HEXAGONAL FERRITES

抄録

  A knowledge of the distribution of divalent metallic (Me²⁺) and trivalent iron (Fe³⁺) cations among seven different sublattice sites of an hexagonal ferrite with W-type structure is interesting and essential in understanding and arriving at the orientation of the magnetic ions as well as non-magnetic ions. Cation distribution in turn is very useful in understanding the variation of various magnetic and electrical properties with varying dopant's concentration. Therefore, the orientation of the magnetic ions of two hexagonal ferrite systems viz., Sr-Zn-Co and Sr-Zn-Li has been arrived at using saturation magnetization values.
