摘要
We report the temperature (T) and oxygen concentration dependences of the penetration depth of grain-aligned YBa2Cu3O7-delta with delta= 0.0, 0.3, and 0.43. The values of the in-plane lambda(ab)(0) and out-of-plane lambda(c)(0) penetration depths, the low-temperature linear term in lambda(ab)(T), and the ratio [lambda(c)(0)/lambda(ab)(0)] were found to increase with increasing delta. The systematic changes of the linear term in lambda(ab)(T) with T-c found here and in recent work on HgBa2Can-1CunO2n+2+delta(n = 1 and 3) are discussed.
