We measured the effect of pressure on the compressional and shear wave velocity (V_P, V_S) as well as density of Fe-bearing bridgmanite, Mg_0.96(1)Fe²⁺_0.036(5)Fe³⁺_0.014(5)Si_0.99(1)O₃, using impulsive stimulated light scattering, Brillouin light scattering, and X-ray diffraction, respectively, in diamond anvil cells up to 70 GPa at 300 K. A drastic softening of V_P by ~6(±1)% is observed between 42.6 and 58 GPa, while V_S increases continuously with increasing pressure. A significant reduction in Poisson's ratio from 0.24 to 0.16 occurs at ~42.6–58 GPa, while VS increases by ~3(±1)% above ~40 GPa compared to MgSiO_3-bridgmanite. Thermoelastic modeling of the experimental results shows that the observed elastic anomaly of Fe-bearing bridgmanite is consistent with a spin transition of octahedrally coordinated Fe³⁺ in bridgmanite. These results challenge traditional views that Fe enrichment will reduce seismic velocities, suggesting that seismic heterogeneities in the mid-lower mantle may be due to a spin transition of Fe in Fe-bearing bridgmanite.
