Abstract

We have prepared powder samples of NaxCoO2⋅yH2O using an alternative synthesis route. Superconductivity was observed in Na0.3CoO2⋅1.3H2O between 4 and 5 K as indicated by the magnetic susceptibility. The bulk compressibilities of Na0.3CoO2⋅1.3H2O, Na0.3CoO2⋅0.6H2O, and Na0.3CoO2 were determined using a diamond anvil cell and synchrotron powder diffraction. Chemical changes occurring under pressure when using different pressure-transmitting media are discussed and further transport measurements are advocated.
