Diluted magnetic ZnxFe2-xO3 nanoparticles are special semiconducting nanoparticles which are recognized for their magnetic properties. A theoretical examination of Zn-doped αFe2O3 nanostructures reveals a range of structural and property variations, offering insights into their potential applications and behavior at the nanoscale. In this regard, Heisenberg’s model and Weiss molecular filed theory is used to describe the magnetic properties of ZnxFe2-xO3 nanoparticles. These theorems inevitably enable to investigate the relationship between magnetic parameters, concentrations, particle size, temperature, and exchange energy. The systematic analysis of mean filed molecular theory shows that ZnxFe2-xO3 exhibits mostly of superparamagnetic property and ferromagnetic ordering. The synthesis and characterization of ZnxFe2-xO3 nanoparticles are scientifically explored, with a focus on tailoring their properties, including biocompatibility, reactivity, biosensitivity, and biodegradability, for optimal performance in in vivo or in vitro applications. The result also indicates that Zn substituted Fe2O3 nanoparticles is a smart material by the virtue of its multiferroicity and multifunction. Besides, the ferrofluid and nanofluid characteristics of ZnxFe2-xO3 nanostructures are investigated for bioelectronics and biomedical application. In addition, the impact of nanotechnology, in ensuring biomedical applications such as ferromagnetic resonance imaging is explored. Magnetic field is usually tuned for effective therapy, medical imaging, and drug delivery. By varying x=2 to 8 at %, the response of ZnxFe2-xO3 nanoparticles to external Rheology such as temperature, pressure, electric fields, and magnetic fields is demystified.
