To maximize the properties of nickel–zinc ferrite nanoparticles (NiZnFNPs), a bioinspired procedure was employed with polyethylene glycol as a capping agent. The produced NiZnFNP was a single phase with crystalline diameters ranging from 22.8 to 35.9 nm, according to XRD, SEM, DRS, FTIR, and VSM characterization data. The addition of PEG improved the spherical morphology of NiZnFNPs, which possessed a spherical morphology with considerable agglomeration. The structure of the hysteresis loop shows that our sample transitioned from ferromagnetic to superparamagnetic nature for 2 g-PEG_NiZnFNPs and low ferromagnetic nature for 4 g-PEG_NiZnFNPs samples. The 2 g-PEG_NiZnFNP was employed for self-heating analysis in hyperthermia (HP) at 165 Oe applied field. It generated enough heat to achieve maximum temperature within the therapeutic temperature range in 300 s. The heating temperature was found to be lower when PEG was added. Owing to the obtained properties of NiZnFNP, is highly auspicious for HP applications with fewer side effects due to their biocompatibility and moderate temperature within the therapeutic range. The heating temperature was found to be lower when PEG was added. The assessed SLP was very high, making it an ideal material for hyperthermia applications. It is noteworthy that the 2 g-PEG induced the properties of the sample better and made it suitable for moderate hyperthermia applications.
