Coexistence of Superconductivity and Spin Density Wave : The Relationship between the Order Parameters of Superconductivity and Spin Density Wave

Superconductivity and magnetism usually try to avoid each other. This feature can be exploited to, for example, levitate a magnet above superconductor. However, the recent discovery of magnetic materials that are also superconductors has reconciled these two physical phenomena that were previously thought to be incompatible. Very recently different experimental investigations have been performed which show the possible coexistence of the two states. Due to the existence of speculation of spin fluctuation mediated superconductivity, the coexistence of magnetic order and superconductivity arise as a very important problem in condensed matter. Different experimental investigations have proved that, under certain circumstances, triplet superconductivity is highly affected by the antiferromagnetic phase or insulating spin density wave order. Hence, this work aimed to discuss about the possible coexistence of superconductivity and spin density wave. This material may be valuable for postgraduate students and researchers who are interested in the study of superconductivity and magnetic order.
