Abstract

This study aimed to synthesize MgFe_1.9Ln_0.1O₄ (where, Ln = Yb, Pr, Gd, and Nd) ferrite nanoparticles via the sol-gel process and investigate their structural, morphological, and magnetic properties for potential hyperthermia applications. X-ray diffraction analysis (XRD) confirmed the cubic spinel structure for all samples. Transmission electron microscopy (TEM) images revealed nanometer-scale dimensions and nearly spherical morphology. Vibrating sample magnetometer measurements (VSM) indicated superparamagnetic behavior, with decreasing saturation magnetization (Ms) observed as Ln³⁺ content decreased. Specific absorption rate (SAR) analysis at 198 kHz demonstrated the influence of Ln³⁺ substitution on magnetic properties. Compared to existing studies, Ln³⁺ substituted (Yb, Pr, Gd, and Nd) nanoparticles demonstrate tunable magnetic properties and enhanced SAR performance, offering a more efficient design for hyperthermia treatment of solid tumors.

期刊介绍： The Journal of Materials Science: Materials in Medicine publishes refereed papers providing significant progress in the application of biomaterials and tissue engineering constructs as medical or dental implants, prostheses and devices. Coverage spans a wide range of topics from basic science to clinical applications, around the theme of materials in medicine and dentistry. The central element is the development of synthetic and natural materials used in orthopaedic, maxillofacial, cardiovascular, neurological, ophthalmic and dental applications. Special biomedical topics include biomaterial synthesis and characterisation, biocompatibility studies, nanomedicine, tissue engineering constructs and cell substrates, regenerative medicine, computer modelling and other advanced experimental methodologies.
