A series of lanthanum-substituted strontium cobalt hexaferrites were synthesized via a simple heat treatment method. X-ray diffraction revealed the presence of M-type hexagonal ferrite and hematite phases in all samples. Magnetic hysteresis loops at room temperature indicated an increase in saturation magnetization with higher lanthanum substitution. This suggests tunable magnetic properties, vital for applications like magnetic devices. The chosen calcination temperatures (950 °C and 1050 °C) and duration (3 hours) during heat treatment influence crystalline structure and magnetic behavior. Overall, the study demonstrates the controllable magnetic properties of the synthesized hexaferrites, crucial for potential technological applications.
