We discuss a model wherein soft gamma-ray repeaters (SGRs), anomalous X-raypulsars (AXPs), and radio quiet isolated neutron stars (RQINSs) are all compactobjects exhibiting superconductivity, namely color-flavor locked quark stars.In particular we calculate the magnetic field decay due to the expulsion ofspin-induced vortices from the star's superfluid-superconducting interior, andthe resultant spin-down rate. We find that, for initial parameterscharacteristic of AXPs/SGRs ($10^{13}
