Magnetism in 2D

Magnetism in 2D

For more than 50 years it has been believed that magnetism cannot exist in two dimensions (2D). Nevertheless, it has recently been demonstrated that the 2D material CrI₃ is indeed magnetic at temperatures below 45 K. The underlying mechanism is, however, very different from that of standard magnets, and a proper theory for 2D magnetism is still lacking. In the present project, the framework required for a quantitative theory of 2D magnetism based on computer simulations will be developed.
