Emergent ferromagnetism and unusual irreversible magnetoresistance in an intercalated van der Waals antiferromagnet

Proceedings of the National Academy of Sciences, Volume 123, Issue 4, January 2026. <br/>SignificanceTuning magnetism is of great interest in the context of two-dimensional (2D) magnetic systems and magnetic memory devices. However, most 2D magnets are limited by low transition temperature and lack of memory effects. Here, we demonstrate that …
