| dc.description | Ultrasonic velocity and attenuation data are presented at T < 1 K for pure KTaO<sub>3</sub> and for KTaO<sub>3</sub>:X where X = Na and Li. Evidence is obtained for coherent tunnelling of Na ions within a correlation volume containing many impurities through barriers with distributed height and asymmetry parameters. Tunnelling is correlated with dipole-glass formation. No evidence of tunnelling is found in KTaO<sub>3</sub> and KTaO<sub>3</sub>:Li. |
