Bulk Antiferromagnetic NiO

• Consider bulk antiferromagnetic NiO
  • $Ni_{\uparrow}$ (pink) spins up and $Ni_{\downarrow}$ (green) align on alternating [111] planes
  • Magnetic contribution ~500x smaller than electrostatic contribution
• "Naive" subtraction reconstruction → prone to noise amplification
• Simultaneous adjoint reconstruction → more robust (independent regularization)
