In the 41 × 41 spin lattice with exchange parameters corresponding to the 2D easy-plane copper ferromagnet and the easy-axis manganese antiferromagnet a vortex-like structure and its energy are calculated in the presence of a single nonmagnetic or magnetic impurity. It is found that the in-plane and out-of-plane vortices are attracted to and centered on the impurity in the easy-plane magnet up to the almost isotropic limit. Layered Cu-halide compounds are found to be good candidates for experimental observation of stable, fixed vortex–antivortex patterns. References [1] L.J. de Jongh and A.R. Miedema, Adv. Phys.
