Abstract
A novel technique for the visualization of antiferromagnetic domains making use of second harmonic generation is used to study the easy-plane antiferromagnet Domain states characterized by small, medium, or large domains are observed. Switching from one state to another can be achieved by a heat treatment above and subsequent cooling below Contributions to the mechanism of this unusual behavior of domains are discussed.
