| 中文摘要 | The effect of magnetic field and disorder on the transport properties of the underdoped Y0.5Pr0.5Ba2Cu3O7 films has been investigated in a broad temperature range in magnetic fields up to 50 T. In ultrathin films with strong disorder, where the mean free path iota corresponds to k(F)iota < 4, a convincing power law resistivity vs. temperature ρ(ab) &SIM; T-2γ (γ = 0.31-0.39) is observed in a very broad temperature range T &AP; 2-40 K. However, in superconducting thicker films with much weaker disorder (k(F)ι > 14 in normal state), the high magnetic field, by suppressing superconductivity, recovers the normal-state transport behavior with the rho(ab) similar to ln T-dependence at low temperature in similar to50 T field. The two different transport behaviors indicate that the normal-state transport properties of the underdoped cuprates are very sensitive not only to the hole concentration but also to the degree of the disorder. |
