Abstract
Antiferromagnetic domains are difficult to reveal directly and consequently are little known. Following a brief introduction to the types of magnetic order and the domain concept, indirect evidence for the existence of domains in antiferromagnets is discussed. Methods for direct observation of antiferromagnetic domains are described, together with their respective advantages. Examples of typical domain structures are included in a review of the relatively few investigations so far conducted. The recent experimental verification of a 25 year old theory of Neel on the absence of spin flop and of domain wall motion in cubic antiferromagnets is described.
