Abstract:
We report a successful crystal growth of Ca2Y2Cu5O10 and anisotropic behavior of magnetic susceptibility associated with an antiferromagnetic phase transition. Single crystals were obtained by the floating-zone method using an infrared radiation furnace. Composition and structural characterization shows that the grown crystals are qualified for physical measurements. The magnetic susceptibility along each crystallographic axis shows a typical behavior of antiferromagnetic phase transition at TN=31 K, and the ordered magnetic moments are found to lie along the b-axis.
