摘要：

We have measured the surface resistance R(s) of laser-deposited Tl2Ba2CaCu2O8 thin films on LaAlO3, substrates. After correcting for leakage of radiation through the films, we find that the normalized surface resistance R(s)/R(N) (with R(N) the normal-state surface resistance at T greater-than-or-equal-to T(c)) is comparable to YBa2Cu3O7 (123) films. The higher transition temperature of the Tl films leads to superior microwave performance in particular at temperatures around T = 77 K and above.
