Correlation between Tc and Lattice Parameters of Novel Superconducting NaxCoO2 yH2O

H. Sakurai, K. Takada, T. Sasaki +3

We synthesized the five batches of the samples of the novel P3 type superconductor, Na${}_x$(H${}_3$O)${}_{y^{\prime }}$CoO${}_2\cdot y^{\prime \prime }$H${}_2$O, by the soft chemical process starting from…
