Magnetic fluctuations near to quantum criticality can have profound effects. They lead to characteristic scaling at high temperature which may ultimately give way to a reconstruction of the phase diagram and the formation of new phases at low temperatures. The ferromagnet UGe2 is unstable to p-wave superconducting order – an effect presaged by the superfluidity in Helium-3 – whereas in CeFePO fluctuations drive the formation of spiral magnetic order. Here we develop a general quantum-by-disorder description of these systems that encompasses both of these instabilities in a unified framework. Moreover, in revealing their fundamentally common origin, we demonstrate how these instabilities can become intertwined to form a pair density wave.
