Higher‐order exchange and quantum effects are widely known to play an important role in the properties of nanomagnets. In article number 2004138, Elton J. G. Santos and co‐workers show that recently discovered two‐dimensional CrI 3 magnets require biquadratic exchange interactions and quantum‐rescaling to describe their long‐range ordering. Metastability of the magnetic domains induces domain walls with different chirality, which is important for the new generation of quantum‐materials‐based technologies.
