Abstract

We analyze an experiment in which two distinct superconducting phases YBa2Cu3O7−δ (Y123) and Y3Ba5Cu8O18−δ (Y358) coexisted. This experiment enabled us to characterize the recently introduced Y358 phase in contrast to the Y123 phase, thus to resolve some discrepancies reported in associated properties of Y358. Specifically, our experiment indicates the transition temperature \(T_{\mathrm{C}}^{\mathrm{mid}}=105~\mathrm{K}\) and 94 K for Y358 and Y123, respectively, and that Y358 has five CuO2 planes and three CuO chains, with Pmm2 symmetry and lattice parameter (a,b,c)=(3.845,3.894,31.093) Å, in agreement with density functional theory predictions for this specific structure.
