Oxidation of TbFe2: Microstructure of oxide-film by both theory and experiment

TbFe<inf>2</inf> owing to its highest magnetostriction finds significant application in defence. However, its quality degradation due to oxidation poses an enormous challenge for being scaled up in a device. To this end, a detailed study by means of both the theory and experiment is performed here to understand the oxide-film overgrowth due to dry, thermal oxidation of TbFe<inf>2</inf>. Then these results are discussed and compared, which is found to be in agreement with each other. Understanding developed in this study would help in tuning the substrate constituents for higher temperature application, where oxidation of the substrate is a major concern.
