The current research work deals with the theoretical study of the interplay between superconductivity and ferromagnetism in iron based high temperature superconductor Fe 1x Pd Te. By developing a model Hamiltonian for the system under consideration and using the double time temperature dependent Green's function technique, we obtained expressions for superconducting transition temperature(T x ), magnetic order temperature (T ), superconducting order parameter( ) and magnetic order parameter ( ). By using the experimental values and by considering some plausible approximations of the parameters in the computed expressions, phase diagrams of versus Tc, Tc versus and T m versus have been plotted. Finally by merging the two phase diagrams, the possible interplay between superconductivity and ferromagnetism in Fe 1x Pd x m Te have been demonstrated. The current ndings are in broad agreement with experimental observations. C
