Dynamic and intense research is being carried out on magnetite nanoparticles because of the vast potential of their usage in various fields such as biomedicine, drug delivery, resonance imaging, making transformers cores, microwave devices, recording material, etc. Various properties of magnetite can be easily optimized by doping with various metal ions. The rare-earth ions have unpaired 4f electrons and strong spin orbit coupling of angular momentum due to which they have higher magnetic moments. In this study, an overview is presented to investigate the effect of rare earth doping in magnetite. The effect of doping on the structural, morphological, magnetic, optical, and electrical behavior of magnetite has been discussed for various applications.
