The collapse of antiferromagnetic order as a function of some quantum tuning parameter such as carrier density or hydrostatic
pressure is often accompanied by a region of superconductivity. The corresponding phenomenon in the potentially simpler case of
itinerant-electron ferromagnetism, however, remains more illusive. In this paper we consider the reasons why this may be so and
summaries evidence suggesting that the obstacles to observing the phenomenon are apparently overcome in a few metallic
ferromagnets. A new twist to the problem presented by the recent discoveries in ferroelectric symmetric systems and new graphite
intercalate superconductors will also be discussed.
