Gd-doped CeO(2) exhibits an anomalously large electrostriction effect generating stress that can reach 500 MPa. In situ XANES measurements indicate the develops in response to rearrangement of cerium-oxygen vacancy pairs. This mechanism is fundamentally different from materials currently use and suggests ceria a representative new family high-performance electromechanical materials.
