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.
