Gravity Anomalies from Deep Mantle Iron Spin Transitions: A Planetary Laboratory for Quantum Gravity Models and General Relativity

Recent results by Gaugne Gouranton et al. (2025, GRL) revealed transient gravity anomalies detected by GRACE during phase transitions in the lowermost mantle (D″). These signals, involving density contrasts of ~100 kg m⁻³, coincide with geomagnetic pe
