The appeared phases and magnetic properties of Sr1-x(La, AM)x ferrites (AM = Na, K) were studied. The prepared samples having the nominal composition of (Sr1-x·(La, AM)x)O·6Fe2O3, contain α-Fe2O3 phase and M-type ferrite phase. However the single phase of M-type ferrites with nominal compositions of (Sr1-x(La0.5Na0.5)x)O· (6-2x)Fe2O3 and (Sr1-x(La0.7K0.3) x)O·(6-x)Fe2O3, where x = 0.2 ∼ 0.8, was obtained by the selection of a tie-line composition. The c-axis of M-type ferrites became shoter with increasing x. Their magnetizations, Curie temperatures and anisotropy fields decreased with increasing the amount of substitution of La-AM for Sr.
