Frustrated spin-1/2 square lattice in the layered perovskite PbVO(3) (2008)

Tsirlin, Alexander A., Belik, Alexei A., Shpanchenko, Roman V., Antipov, Evgeny V., Takayama-Muromachi, Eiji, Rosner, Helge

We report on the magnetic properties of the layered perovskite PbVO(3). The results of magnetic susceptibility and specific heat measurements as well as band structure calculations consistently...

$^{17}$O NMR Measurements on Superconducting Na$_{0.35}$CoO$_{2} \cdot y$H$_{2}$O (2005)

Ihara, Yoshihiko, Ishida, Kenji, Yoshimura, Kazuyoshi, Takada, Kazunori, Sasaki, Takayoshi, Sakurai, Hiroya, ...

An $^{17}$O NMR measurement was performed on nonoriented polycrystalline Na$_{0.35}$CoO$_2 \cdot y$H$_2$O with superconducting (SC) transition temperature $T_\text{c} = 4.6$ K. A weak temperature...

Possible unconventional superconductivity in Na$_x$CoO$_2$yH$_2$O probed by $\mu$SR (2003)
