Sound velocity in perovskite manganites La0.67Ca0.33MnO3 with different grain sizes
The longitudinal and shear sound velocities in colossal magnetoresistive material La0.67Ca0.33MnO3 sintered at 1100, 1250 and 1350 °C with average grain size 1, 3 and 5 μm, respectively, have been measured from 80 to 300 K using the pulse-echo-overlap method. A pronounced increase in the longitudina...
