Abstract
Ferromagnetism and superconductivity had been thought to be mutually repulsive.
Even when superconductivity has been thought as arising from magnetic mediation
of paired electrons, it was believed that superconductivity occurs in the paramagnetic
phase. A great effort has been made to prove this, On the contrary in 2000 the
two phenomena were found to coexist in UGe2 and in others as URhGe and ZrZn2
in which the same electrons are responsible for both phenomenon. We study the
coexistence of the two phenomena particularly in ZrZn2 and demonstrate that for
certain values of the parameters of triplet superconductivity and ferromagnetism is a
possibility
