We report the discovery of striking antiferromagnetic domain patterns revealed by real-space Bragg coherent X-ray diffractive imaging. As the system cools, magnetic regions form bubble and zebra-like stripe patterns. Tiny topological defects appear and disappear with temperature, while domain boundaries fluctuate near the transition, offering new insight into how magnetic order emerges at the nanoscale.
