    Coexistence of Ferromagnetism and Superconductivity in ZrZn2
    (Addis Ababa University, 2007-07) Demeke, Birhanu
    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
