| description | In this study, the ab initio density functional theory (DFT) approach is used to investigate the effect of Holmium (Ho) on the magnetic and mechanical properties of Nd2Fe14B magnets. Neodymium-based permanent magnets (Nd2Fe14B) are the potential permanent magnets to be used in various applications such as wind turbines and electric vehicles. These magnets possess high magnetic field strength and resistance to demagnetization. However, they suffer from low operating temperatures below 585 K. Substitution of Nd with Ho enhances the magnetic strength of the Nd2Fe14B permanent magnet. NdHoFe14B magnets are found to be thermodynamically stable due to negative heats of formation, which is in good agreement with the calculated density of states. Partial substitution of Nd with Ho improves the stability and the magnetic strength of Nd2Fe14B permanent magnets. The findings will provide insight into the future development of permanent magnetic compounds with good magnetic strength. |
