Abstract:
In the study of nanoparticles in the area of biomedicine, more specifically to combat cancer, in many cases, it becomes necessary to search for small particle sizes and low values of saturation magnetization and magnetocrystalline anisotropy. In this work, we synthesized, using the sol-gel/combustion method, five mixed cubic manganese and zinc ferrites doped with different percentages of cerium. In the reaction, we used citric acid as fuel. The samples were characterized by X-ray diffraction, magnetization, and ferromagnetic resonance. The results showed that the ferrite with 3% Ce had the best values of magnetization and anisotropy for biomedical applications such as the treatment of cancer.
