Schematic P-T phase diagram of Sr3Ir2O7. The phase boundary (TN) of paramagnetic (PM) insulator phase and magnetically ordered insulator phase and also the structural phase transition boundary (TS) are based on our Raman data (squares and asterisks on the phase boundary). The black dot on the TN (or TS) phase boundary represents the structural phase transition reported in the reference.25 The insulator to metal transition (IMT) region is taken from the references.26,28,29
