[en] We propose a new scenario for the magnetic collapse under pressure in ferropericlase (FP) ($\text{F}{\text{e}}_{1/4}\text{M}{\text{g}}_{3/4}$)O without the presence of intermediate spin state, which contradicts the mechanism proposed in (2013 Phys. Rev. B 87 165113). This scenario is supported by results of combined local density approximation + dynamical mean-field theory method calculations for the paramagnetic phase at ambient and high pressures. At ambient pressure, calculation gave ($\text{F}{\text{e}}_{1/4}\text{M}{\text{g}}_{3/4}$)O as an insulator with Fe 3d-shell in high-spin state. Experimentally observed high-spin to low-spin state transition of the $\text{F}{\text{e}}^{2+}$ ion in the pressure range of 35–75 GPa is successfully reproduced in our calculations. The spin crossover is characterized by coexistence of $\text{F}{\text{e}}^{2+}$ ions in high and low spin state but intermediate spin state is absent in the whole pressure range. Moreover, the probability of Fe ion ${\text{d}}^7$ configuration with $S=1$ grows with pressure due to shortening of metal–oxygen distance. Also, no metal–insulator transition was obtained up to the pressure 140 GPa in agreement with experiment. (paper)
