In this study, a series of M-type lanthanum-substituted strontium cobalt hexaferrites, denoted as Sr0.5Co0.5LaxFe12-xO19 (with x values of 0.0, 0.05, 0.15, and 0.2), were meticulously synthesized using a straightforward heat treatment method. The subsequent calcination process at 950 °C and 1050 °C for 3 hours in a muffle furnace, followed by gradual cooling to room temperature, ensured the formation of hexagonal ferrites with controlled lanthanum content.
The structural and magnetic characteristics of the prepared samples were thoroughly investigated using X-ray diffraction (XRD) technique and magnetic hysteresis loops, respectively. The XRD analysis unveiled the presence of M-type hexagonal ferrite and hematite phases in all samples, indicating the successful synthesis of the desired materials. Notably, the magnetic hysteresis loops analysis at room temperature demonstrated a discernible increase in saturation magnetization with the progressive substitution of lanthanum.
This research contributes valuable insights into the tailored fabrication of M-type hexaferrites with tunable magnetic properties, holding significance for applications in diverse fields such as electronics and magnetism.
