Figure 5: Ordered states of the model with distortions (d-DSM).
From: Intermediate magnetization state and competing orders in Dy2Ti2O7 and Ho2Ti2O7
Within the range of parameters fixed by the experimental susceptibility data, and depending on the difference ΔJ3 between the third-nearest-neighbours exchange constant, the system orders into two possible states. (a,b) Cut along [100] of the two ordered states. The non-shaded regions correspond to the unit cells. (c) Ranges in ΔJ3 where each state is observed. (d) The signature of this transition in the specific heat divided by temperature, compared with the results obtained for DTO in refs 12, 28.
