Unconventional superconductivity can be induced in the vicinity of quantum critical point as a consequence of suppression of long range magnetic ordering as function of control parameter. In the iron pnictide superconductors, there is growing evidence of unconventional superconductivity with unusual gap symmetry and phase coexistence close to the phase boundary between spin density wave (SDW) and superconductivity. Compositions that lie adjacent to this phase boundary are of great importance as they offer the possibility for enhanced or suppressed superconductivity or magnetism depending on what side they are on the phase diagram. In this proposed work, we wish to study the pressure effects on the structural properties and the possible induction of quantum criticality at the lowest base temperature possible.
