Penetration Depth Measurements and Associated Phenomenology in High-Tc Superconductors
15 November 1989
Measurements of the penetration length lambda of c-axis oriented thin films of YBa sub 2 Cu sub 3 O sub 7 in magnetic fields H as high as 14 T enable a determination of the transition temperature T sub c(H) by extrapolation to lambda=infinity. For fields in the range 1 T ~
