The substitution of the strontium site by divalent and trivalent ions improved the TCF, accompanying the relaxation of elastic anomaly. The tolerance factor, t, was calculated for a pseudo cubic block to study the contribution of the structural factor to Curie temperature, T-C, and the temperature of elastic anomaly, T-ea, for each sample. T-ea showed no apparent tendency with t, whereas T-C increased as t decreased.piezoelectric propertytemperature coefficient of resonance frequencytolerance factoryoungs modulusferroelectricsbi2srnb2o9catext::journal::journal article::research article
