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<SUB>0.5</SUB>Fe<SUB>11.3</SUB> O<SUB>19</SUB>. It was confirmed that the Zn-stabilized La M-type ferrite had a hexagonal symmetry (P6<SUB>3</SUB>/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<SUP>-1</SUP> at room temperature at the applied field of 1200kA⋅m<SUP>-1</SUP>, and the Curie temperature is 649K.
