Resumo
The effect of lattice strain on the exchange interaction constants of Cr2CFBr MXene was studied using first-principles calculations. Knowledge of the exchange constants made it possible to simulate the dependence of the Néel temperature TN on the lattice strain ε of the MXene using the mean-field method. It was found that with increasing tensile strain, TN changes non-monotonically, reaching a maximum value at ε = 0.1. Compressive strain up to ε = −0.11 monotonically decreases the Néel temperature, but beyond ε < −0.11, it leads to a rapid increase in TN. It is shown that in the Cr2CFBr system, at a strain of ε = −0.11,an “order–order” phase transition occurs, where the Néel-type antiferromagnetic state transforms into a
stripe-type antiferromagnetic state.
