ABSTRACT: The coexistence of
superconductivity and spin density wave in SmO1-xFxFeAs
is theoretically studied using the model Hamiltonian which contains BCS type
superconductivity and spin density wave terms. Employing green function
formalism, the expression for the spin density wave order parameter (M) and
expression for spin density wave transition temperature TSDW is
obtained. The interplay between the
superconductivity and spin density wave is examined in these parameters and the
coexistence of the two states is established in the order parameter range of 0.1≤MmeV≤0.13 which is
seen to be in broad experimental agreement.
