| 中文摘要 | We report on a study of the temperature dependence of thermal conductivity and resistivity of Zn-doped La2CuO4 with slow cooling and slow warming after quenching. The thermal conductivity above 130K is reduced by quenching. A minimum appears at 130K, which is not sensitive to the cooling rate. Moreover, the low-temperature thermal conductivity is not affected by changing the cooling rate, which is consistent with the fact that the resistivity is also insensitive to the cooling rates at low temperatures. In the low-temperature region (T < 125 K), the resistivity in the nonmetallic regime does not change. with the change of cooling rate and it can be described with the variable range hopping law. We also found that both thermal conductivity and resistivity do not show any trace of anomaly at T-N for both the parameters. This suggests that the dominate contribution in transport properties is not from the energy band, and this is in opposition to Anderson's theory of spin-charge separation. These contradictions can be explained by the polaron theory. |
