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