Van der Waals Antiferromagnets: From Early Discoveries to Future Directions in the 2D Limit

Rahul Kumar, Je-Geun Park

The emergence of a long-range magnetic order in the atomically thin, two-dimensional (2D) limit has long remained a fundamental question in condensed matter physics. The advent of…
