However, their formation has been limited to a small number of materials due to the delicate balance of magnetic energies involved. In this study, we report the irreversible formation of skyrmions in Nd2Fe14B, a rare-earth permanent magnet characterized by large magnetic anisotropy. Remarkably, these magnetic topological defects exist over a wide range of temperatures and magnetic fields (295？565？K and 0？0.1？T) due to the high Curie temperature and significant magnetic anisotropy of Nd2Fe14B. Our findings not only unveil a new material where skyrmions can form but also open up possibilities for exploring topological defects in various magnetic systems, including strong hard magnets.
