Description

Neodymium-based permanent magnets (Nd2Fe14B) are the potential permanent magnets for use in various applications such as wind turbines and electric vehicles due to their high magnetic field strength and resistance to demagnetisation. However, they suffer from low operating temperatures below 585 K and poor mechanical and vibrational properties. In this study, we investigate the effect of Ce on the magnetic and mechanical properties of Nd2Fe14B magnets using the ab initio density functional theory (DFT) approach. The NdCeFe14B magnets are found to be thermodynamically and mechanically stable. The alloying of Nd with Ce improves the stability and magnetic strength of Nd2Fe14B permanent magnets. The findings will provide insight into the future development of permanent magnetic compounds with good magnetic strengths.
