Abstract

The crystal structure and magnetic properties of Zn-stabilized La M-type ferrite with magnetoplumbite structure were studied. The single phase of M-type ferrite was obtained by using conventional ceramic techniques with nominal composition of LaZn_0.5Fe_11.3O₁₉. It was confirmed that the Zn-stabilized La M-type ferrite had a hexagonal symmetry (P6₃/mmc) with lattice constants of a=0.5890, c=2.2926nm. The c-axis length was smaller than that of Sr or Ba M-type ferrite. The magnetization of this ferrite is 81.4μWb·m·kg^-1 at room temperature at the applied field of 1200kA·m^-1, and the Curie temperature is 649K.
