Erratum to: Enhanced piezoelectric properties of off-stoichiometric strontium bismuth tantalate Sr_0.8Bi_2.2Ta₂O₉ ceramics (10.1007/s00339-004-3073-x)

The above article was published with the errors in the piezoelectric constants (d₃₃, d₃₁, d₁₅) of S_0.8B_2.2T ceramics in main text of p. 133 and Table 3 of p. 134. The article showed that the d₃₃, d₃₁, and d₁₅ values are 10.8, 5.2, and 6.0 pC/Nin themain text and 6.0, 13.0, 10.2 pC/N in Table 3, respectively. The correct piezoelectric constants are d₃₃ = 13.0, d31 = 6.0, and d₁₅ = 10.2 pC/N, respectively. The readers can obtain these values by the relevant equations [1] using the electromechanical coupling factors in Table 2 and dielectric, elastic constants in Table 3. The authors regret this oversight.
