Simulation of single-crystal magnetization. Single-crystal experimental magnetization (blue curve) measured at T = 0.03 K and a sweep rate of 0.1 T s⁻¹ for a magnetic field oriented parallel to the triangle’s planes and along the easy axis (y-axis in Fig. 6), superimposed on the simulated dynamical magnetization at the same temperature, sweep rate, and field orientation, by solving Eq. (8) on the basis of 56 out of the 256 states obtained from our model and reported in Supplementary Fig. 8, for the following numerical values of the transition rates appearing in the equations: Γ _Cr = 10⁵ Hz/(cm⁻¹)³ ≫ Γ ₁ = 10⁻⁷ × Γ _Cr > Γ ₂ = 10⁻³ × Γ ₁, and γ _Cr = 10¹⁶ Hz² ≫ γ ₁ = 10¹² Hz² > γ ₂ = 10⁻³ × γ ₁
