This research’s prime focus was to synthesize the nano-sized Nd[Formula: see text]-substituted Sr[Formula: see text]Nd x Fe 8 O[Formula: see text] T-type hexaferrites with the composition ([Formula: see text], 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 25.10[Formula: see text]nm to 25.39[Formula: see text]nm. The P–E loops indicated that the materials’ lossy behavior decreased with Nd[Formula: see text] content, unveiling an improvement in ferroelectric behavior. The saturation magnetization (M s ) values varied from 4.79[Formula: see text]emu/g to 18.41[Formula: see text]emu/g and coercivity from 1955.90[Formula: see text]Oe to 2614.34[Formula: see text]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.
