A series of M-type lanthanum-substituted strontium cobalt hexaferrites, Sr0.5Co0.5LaxFe12-xO19 (x = 0.0, 0.05, 0.15, and 0.2), were synthesized through heat treatment at 950 °C and 1050 °C, followed by slow cooling. X-ray diffraction revealed the presence of M-type hexagonal ferrite and hematite phases. Magnetic hysteresis loops at room temperature exhibited an increase in saturation magnetization corresponding to higher lanthanum substitution levels.
