Numerical simulation of the magnetic inhomogeneity (red = magnetism, blue = superconductivity) caused by replacing 1% of the indium atoms in a superconductor (CeCoIn5) with cadmium atoms. The field of view is approximately 100 nanometers along each edge. (Cover Image from Seo et al., Nature Physics, 10, February 2014).
