Fig. 4: Magnetic states emerging at Cr (A) lattice by tuning the MAE.
From: Topological magnetism in diluted artificial adatom lattices
a Snapshot of the in-plane AFM Cr antiskyrmion when Kzz − Kxx = Kzz − Kyy = − 0.01 meV. With this MAE the spins can align isotropically in-plane, with the in-plane AFM state shown in inset being the ground state. b, c The building blocks of the in-plane AFM antiskyrmion, which are two in-plane FM antiskyrmions coupled antiferromagnetically. d Snapshot of the OOP AFM Cr antiskyrmion after flipping the sign of the MAE (Kzz − Kxx = Kzz − Kyy = 0.01 meV), which leads to an OOP AFM order. e, f The building blocks of the AFM antiskyrmion, which are two FM antiskyrmions coupled antiferromagnetically.
