Role of the inner copper-oxide plane in interlayer Josephson effects in multi-layered cuprate superconductors

Y. Nomura, R. Okamoto, T. Mizuno +4

We find systematic signatures suggesting a different superconducting nature for a triple-layered cuprate Bi${}_2$Sr${}_2$Ca${}_2$Cu${}_3$O${}_{10+\delta }$ with respect to a double-layer through t…
