摘要：

Using a newly devleoped EPR spin-probing methodology, we have measured magnetic penetration depth for Tl2Ba2Ca2Cu3Ox and Bi2Ca2SrCu2Ox. The temperature dependence of is found to follow the relationship = 0[1-(T/Tc)4]-1/2, with 0=2520 100 A and Tc=119 K for Tl2BaCa3Cu3O7.8+x and 0=2700 100 A with Tc=84 K for Bi2Ca2SrCu2Ox. © 1990 The American Physical Society.
