The longitudinal and shear sound velocity in colossal magnetoresistive La1-xSrxMnO3 (x = 0.0, 0.05, 0.15 and 0.3) were measured using the pulse-echo-overlap technique in the temperature range of 80 to 300 K. An abrupt increase in the longitudinal velocity was observed immediately below the insulator...
