Abstract
An impurity in an unconventional superconductor perturbs the order parameter out to distances of order ξ(T). When the order parameter is ‘‘ferromagnetic’’ in character a localized flow of supercurrent is also induced; this supercurrent creates a magnetic field at the site of the impurity. We discuss these supercurrents, and estimate the size of the resulting magnetic field.
