  Most canted antiferromagnets are also anomalous Hall antiferromagnets (AHE
AFMs), i.e. they have an anomalous Hall response and other responses with the
same symmetry requirements. We suggest that AHE AFMs are promising materials as
hosts for high-temperature quantum anomalous Hall effects. By considering
models of two-dimensional (001) perovskite layers with strong spin-orbit
coupling that isolates an effective total angular momentum $\tilde{j}=
\frac{1}{2}$ subspace of the $t_{2g}$ manifold, we propose a strategy to
engineering quantum anomalous Hall antiferromagnets.
