dc.description.abstract Permanent magnets (PM) find widespread application in energy conversion, telecommunication, data storage, sensors, electronic gadgets, etc. Even though the market for PM is dominated by rare earth (RE) based magnets like Nd-Fe-B and Sm-Co, the recent crisis of RE elements and supply constraints have evoked the necessity of new PM materials for sustainable development. Owing to the predicted high value of (BH)(max), the abundant availability of constituent elements (Fe, Ni), and presence in natural meteorites, L1(0) FeNi has drawn the attraction of the scientific community. Therefore, in this article, L1(0) FeNi (tetrataenite) is extensively reviewed as one of the most suitable candidates for future permanent magnetic material. Although L1(0) FeNi has shown immense potential for PM application due to its high magnetocrystalline anisotropy and magnetic saturation, the bulk synthesis of this material is not yet achieved. The problems in laboratory synthesis of L1(0) FeNi and the technological limitations for practical use are dominated by the slow diffusion of Ni in the FeNi lattice around the low order-disorder temperature (similar to 593 K). Artificial techniques with a low-temperature synthesis of ordered L1(0) FeNi are highlighted and the properties of L1(0) FeNi thin films are also presented coherently.
