Popis: M-hexaferrite single crystals of chemical formulae BaFe12-2xIrxO19 with Me = Zn, Co and 0.3 < x < 0.9, were grown from a Bi2O3 flux. Crystal structure refinement studies showed that Ir and Zn cations are exclusively located on octahedral sites in R structural blocks. Saturation magnetizations of these ferrites are consistent with Gorter's spin arrangement, considering there to be a magnetic moment of 5μB on the Ir4+ cations.
