摘要：

Single crystals of PdCoO2 have been successfully grown using the metathetical reaction. Crystals have a form of well-habited hexagonal platelet shape with maximum size 0.8 x 0.8 x 0.1 mm(3). Anisotropic electrical and magnetic properties have been cralified for the first time. Magnetic susceptibilitiy only in the direction of the c-plane is found to Show a distinctive cusp at 24 K, suggesting a long-range magnetic ordering. rho(perpendicular to) and rho(parallel to) at 260K are 5 and 700 mu Omega cm, respectively. Residual resistivities rho(perpendicular to) and rho(parallel to) at 16K are 0.6 and 108 mu Omega cm, respectively. Electrical resistivities in both directions are found to show metallic temperature dependence.
