Studies on colossal magnetoresistance La1-xCaxMnO3 (x = 0.25, 0.33 and 0.45) by ultrasound method
La1-xCaxMnO3 which exhibits colossal magnetoresistance (CMR) effect for x = 0.25, 0.33 and 0.45, was subjected to ultrasound investigations. For all samples, temperature-dependent electrical resistivity measurements showed a metal-insulator transition identified by a peak in resistivity, typical tra...
