The appeared phases and magnetic properties of Sr<SUB>1-x</SUB>(La, AM)<SUB>x</SUB> ferrites (AM=Na, K) were studied. The prepared samples having the nominal composition of (Sr<SUB>1-x</SUB>⋅(La, AM)<SUB>x</SUB>)O⋅6Fe<SUB>2</SUB>O<SUB>3</SUB>, contain α-Fe<SUB>2</SUB>O<SUB>3</SUB> phase and M-type ferrite phase. However the single phase of M-type ferrites with nominal compositions of (Sr<SUB>1-x</SUB>(La<SUB>0.5</SUB>Na<SUB>0.5</SUB>)<SUB>x</SUB>)O⋅(6-2x)Fe<SUB>2</SUB>O<SUB>3</SUB> and (Sr<SUB>1-x</SUB>(La<SUB>0.7</SUB>K<SUB>0.3</SUB>)<SUB>x</SUB>)O⋅6-x)Fe<SUB>2</SUB>O<SUB>3</SUB>, 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.
