Abstract
Antiferromagnetic domain boundaries in single-crystal NiO specimens have been examined by transmission electron microscopy. The domain boundaries were found to move through the matrix as a result of beam-induced thermal stresses. Movement of the boundaries was restricted by dislocations. Some evidence is given to show that domain boundaries may serve as nucleation sites for the reduced species in gaseous reduction of NiO. The presence of vacancy loops in nickel oxide has been established.
