Magnetism and superconductivity are apt to be found in a number of strongly correlated electron systems. Celebrated examples are cuprate superconductors and their recent iron-based analogs. As doping is varied, these substances move between magnetism and superconductivity. It is thus no wonder that, many surmise an inherent connection between these two phases. It is quite possible that, the same electronic interaction is controlling them.
This viewpoint discusses another aspect on the connection between magnetism and superconductivity. This discussion strongly suggests that, a mathematical description may be established generic to them. If this were the case, two things would be clear: (1) competitions between magnetism and superconductivity must exist as a rule and (2) understanding one could help comprehend the other.
