abstract
We have measured out-of-plane resistivity ρc for La2-xSrxCuO4 under anisotropic pressure, c-axis compression, which decreases ρc, reduces Tc drastically, whereas c-axis extension, which increases ρc, enhances Tc from 38 K at ambient pressure to 51.6 K at 8 GPa. We find that the variation of Tc scales as a function of ρc, and that the c-axis pressure coefficient is much stronger than the ab-axis one. These findings imply that Tc depends primarily on the interlayer, rather than the in-plane, lattice parameter.
