摘要：

A bulky (7X3X3 mm(3)) single crystal of Ca2CuO3 has been successfully prepared by the traveling-solvent-floating-zone (TSFZ) method using CuO excess solvent. An optimum solvent composition for growth of the titled compound was found to be around 9 in CuO/CaO molar ratio R under 0.1 MPa oxygen partial pressure. The obtained R value considerably deviates from the estimated one based on the reported equilibrium phase diagrams. Anisotropic magnetic susceptibilities of the prepared single crystal were observed, In particular an anomalous thermal behaviour of the susceptibility under the magnetic field along [001] and [010] indicates an appearance of three-dimensional antiferromagnetic order below around 8 K.
