  Controlling the magnetic order of antiferromagnets is challenging due to
their vanishing net magnetization. For this reason, the study of local spin
textures in antiferromagnets is restricted by the difficulty in nucleating such
states. Here, using atomistic simulations we demonstrate a method for
nucleating localized spin textures in the grains of thin film antiferromagnet,
$\gamma$-IrMn$_3$. Utilising the exchange bias coupling between a ferromagnet
and an antiferromagnet, we set the spin texture in the latter from a predefined
spin texture in the former by means of a thermal cycling procedure. The local
textures set in the antiferromagnetic grains are shown to be stable against
field perturbations. We also discuss how various material parameters affect the
efficiency of the setting and the characteristics of these set textures. The
setting of antiferromagnetic spin textures provides a potential route to
antiferromagnetic spintronic devices with non-collinear spin states such as
skyrmions, bubbles and domain walls.
