Revealing emergent magnetic charge in an antiferromagnet with diamond quantum magnetometry

A. K. C. Tan, H. Jani, et al.

This groundbreaking research by Anthony K. C. Tan and colleagues demonstrates diamond quantum magnetometry to reveal topological textures in haematite, uncovering emergent magnetic charge distributions. Their findings establish an exciting duality between staggered vorticity and magnetic charge, showcasing potential for exploring quantum materials.

Abstract
This paper demonstrates the use of diamond quantum magnetometry (DQM) to image topological textures in the antiferromagnet haematite (α-Fe₂O₃) and reveals the presence of monopolar, dipolar, and quadrupolar emergent magnetic charge distributions. The study establishes a duality relation between staggered vorticity and magnetic charge, associating antiferromagnetic Bloch merons with spatially extended emergent magnetic monopoles. The findings highlight the potential of DQM for exploring emergent phenomena in quantum materials.
