## Abstract Very high lateral ionic conductivities in epitaxial cubic yttriaβstabilized zirconia (YSZ) synthesized on singleβcrystal SrTiO~3~ and MgO substrates by reactive direct current magnetron sputtering are reported. Superionic conductivities (i.e., ionic conductivities of the order βΌ1 Ξ©^β1^c
A 9 mol% Y 2 O 3 -stabilized ZrO 2 specimen was annealed in boiling water for 1200 h, and the phase structure was examined by XRD and the chemical states of zirconium, yttrium and oxygen were examined by XPS. After annealing, the phase of the specimen remains entirely cubic, and the chemical states
