| 英文摘要 | Internal friction measurement of perovskite manganite La0.67Ca0.33MnO3 shows that there are three peaks in the spectra of internal friction Q(-1)(T) at temperatures 260 K, 222 K and 105 K, respectively. It is concluded, that the peak at 105 K is related to the electronic phase separation in ferromagnetic region. The broad peak around 222 K is composed of two sub-peaks located at 222 K and 234 K. This broad peak is of the characteristic of relaxation originating from the thermally activated motion of insulating and conduction domains. The activation energy and the relaxation time at infinite temperature are determined as 0.32 eV, 2.0 x 10(-12) s for 222 K subpeak and 0.38 eV, 2.5 x 10(-13) s for 234 K subpeak, respectively. |
