The apparent phases and magnetic properties of ferrites of the RE2O3-AM2O-Fe2O3 system (RE=Y, La, Ce, Pr, Nd, Sm, Gd, and AM=Na, K, Rb) were studied. The observed phases were classified according to the combination of rare earth metal and alkaline metal. M-type ferrites, which have a magnetoplumbite structure, were obtained in the La2O3AM2O-Fe2O3system (AM=Na, K, Rb). M-type ferrites were synthesized at over 1473 K for the La-Na system, 1573 K for the La-K system, and 1673 K for the La-Rb system. A single phase of M-type ferrite was prepared in (La1-xKx)O·6Fe 2O3 at x=0.2. The magnetization of (La0.8K0.2)O·6Fe2O3 is 86μWb·m·kg-1,and the Curie temperature is 708 K.
