A x Pb ( Zn 1/3 Nb 2/3 )O 3 –(1– x ) Pb ( Zr 0.95 Ti 0.05 ) O 3 ( x PZN –(1– x ) PZT ) system close to antiferroelectric–ferroelectric ( AFE – FE ) morphotropic phase boundary has been prepared and investigated. The XRD results reveal PZN addition induces a phase transition from the orthorhombic ( AFE ) to rhombohedral ( FE ) phase through a phase coexistence region ( AFE + FE ). The polarization–electric field ( P–E ) measurements indicate that the AFE phase can be induced into a metastable FE ( FE m ) phase. And the FE m can recover to AFE around a critical temperature indicated by temperature‐dependent P–E loops. A composition‐temperature phase diagram was generalized within a certain range of PZN content in which an AFE – FE phase boundary connecting orthorhombic antiferroelectric to rhombohedral ferroelectric phase zones is formed near room temperature.
