for a broad range of applications including miniaturized spintronics and magnetoelectric
sensors. Owing to the general air sensitivity of 2D magnets, the understanding of ambient
effects on 2D magnetism is critical. Apparently, the nature of itinerant ferromagnetism
potentially makes metallic 2D magnets insensitive to environmental disturbance.
Nevertheless, our systematic study showed that the Curie temperature of metallic 2D Fe 3 …
