Abstract

The X and W phases exist in the LaxZnxBa1-xFe12-xO19 ferrites in the high temperature phase region. The Curie temperatures of the X and W phases were obtained at x=0 as 518℃ and 534℃ respectively. The substitution of Ba, Fe ions in the W phase by La, Zn ions is possible in the range of xf and anisotropy field HA descrease with increasing x for the W phase, whereas the saturation magnetization σs increase and the crystal anisotropy constant is approximately a constant value.
