    • Another interesting possibility is that moments could form on the neighboring Fe but that these could form singlets where the four Fe atoms around the Cu could have canceling moments due to antiferromagnetic interactions between them. Recalling that the four Fe atoms around a Cu substitutional are second neighbors on the Fe square lattice, the case where the Fe moments are aligned would correspond locally to the checkerboard (nearest-neighbor antiferromagnetic) order, while the antiferromagnetic state with canceling Fe moments would correspond locally to the SDW pattern.
