A Model for Superconductivity in Ferromagnetic ZrZn2
Superconductivity
2009-11-07 v2
Abstract
This article proposes that superconductivity in the ferromagnetic state of ZrZn is stabilized by an exchange-type interaction between the magnetic moments of triplet-state Cooper pairs and the ferromagnetic magnetization density. This explains why superconductivity occurs in the ferromagnetic state only, and why it persists deep into the ferromagnetic state. The model of this article also yields a particular order parameter symmetry, which is a prediction that can be checked experimentally.
