Abstract：Pnictide oxide superconductor GdFePO has been synthesized by a two‐step solid reaction method .Gd‐Fe‐P ternary alloy is firstly prepared using pre‐melting technology .T he superconductivity at a‐round 6 .1 K in GdFePO is observed .An annealing treatment done after synthesis could effectively reduce the dislocation density and furthermore affect the superconducting transition .Detailed evidences based on transmission electron microscopy analysis reveal the relationship between the adjustable superconducting properties and the dislocations along[001] orientation of GdFePO .
