Abstract
The effect of Antiferromagnetic order on superconducting order parameter ( delta) in Iron-pnictide
superconductor has been studied by using double time retarded Green’s Functions Technique, and
expression for ( has been obtained. The expression is found to be depending on the
Antiferromagnetic order parameter (η) along with temperature (T). It has been found that at
superconducting order parameter and antiferomgnetic order parameter decreasing with increasing
temperature but superconducting order parameter becomes almost zero at Transition
Temperature. Results also shows that the Co-Existence of Magnetism and Superconductivity.
Keywords: Iron-pnictide, Antiferromagnetic order , Co-Existence, High Tc Superconductor
