Extract

The difference of domain switching amount of 3 mol% R2O3−ZrO2 (R = Yb, Y, Dy, Gd, Eu, Sm) pseudo-single crystals with additive cation species was investigated from the microstructural aspect. The switching amount of Yb, Y, Dy, and Gd substituted ZrO2 was three times higher than that of Eu and Sm. The amount corresponded to the volume fraction of the t′-phase, and it indicated that phase separation proceeded, especially in Eu and Sm substituted ZrO2.
