Evaluation of nano-sized hexaferrites for hyperthermia applications

This research’s prime focus was to synthesize the nano-sized Nd3+-substituted Sr2−xNdxFe8O14 T-type hexaferrites with the composition (x=0.00, 0.05, 0.1 and 0.15) to augment indulgence of their magnetic properties. Such insights are essential for exploring the imminent applications of these materials in the biomedical field. The X-ray diffraction patterns revealed that the samples were single-phase hexagonal ferrites. The crystallite size varied from 25.10nm to 25.39nm. The P–E loops indicated that the materials’ lossy behavior decreased with Nd3+ content, unveiling an improvement in ferroelectric behavior. The saturation magnetization (Ms) values varied from 4.79 emu/g to 18.41 emu/g and coercivity from 1955.90 Oe to 2614.34 Oe. The coercivity value suggests that the material might be used in data storage, recording media devices and storage and permanent magnet applications. The heat generated during the alternative magnetic field hyperthermia process establishes these materials as a formidable intervention for decisively targeting tumors, leveraging elevated temperatures to disrupt their growth and survival, paving the way for a significant breakthrough in cancer therapy.
