□ Electron-irradiation induces anomalous large defect clusters, which is considered to be charged oxygen dislocation loops lying on (111) planes, in YSZ and CeO2. □ The defect clusters induce strong stress and strain field due to the electric field induced by charge accumulation as well as elastic one. □ The charged defect multiplies dislocations when it grows to a critical size in YSZ (and also in CaF2). □ This investigation suggests an important role of the selective elastic displacement damage in oxygen sublattice in fluorite structure ceramics.
