Abstract
Three hexaferrites CaFe(4)Me(8)O(19) (Me = Al, Cr, or Co) are prepared and found to have M-structure. The substitution of Al+3 or Cr+3 ions in the lattice reduces the magnetization, whereas Co+3 enhances it wit h higher Curie temperature. These differences are explained on the bas is of exchange interactions within the sub-lattices. Static electrical resistivity of the samples is also studied and results show that they are semiconductors.
