摘要：
Thin plate-like [Ca-2(Co1-xCux)(2)O-4](y)CoO2 single crystals were successfully grown by the flux method using SrCl2 solvent. The largest crystal size was approximately 3 x 3 x 0.01 mm(3). The copper concentrations, x, in the crystals were found to be depending on each crystal, suggesting a certain solid-solution range of copper in the present system. The obtained crystal showed low resistivity (similar to4.3mOmegacm) and high Seebeck coefficient (similar to160muVK(-1)) at 300K. The crystal showed anisotropic magnetization with larger magnetization under H//c. Irreversible magnetization behavior below similar to90K was also found under H//c.
