Descripción

In this work, the ferromagnetic phase transition in a monolayer of chromium triiodide (CrI3) was examined. Employing a microcanonical ensemble approach, entropy was evaluated as a function of internal energy and magnetization was calculated with respect to energy across various spin configurations. In this way, a methodology was found to observe phase transitions using thermodynamic quantities other than specific heat. The Hubbard model was used to characterize the exchange interactions, defined by a first-neighbor exchange energy of J=2.37 meV.
