摘要：

Large single crystals of (La1-xCax)2CaCu2O6 were synthesized by the travelling solvent floating zone (TSFZ) technique. The dimension of the grown boules was typically 4 mm phi x 30 mm long with the c-axis perpendicular to the growth direction. After oxygen loading at 1080-degrees-C in 400 atm Of O2, they became superconductive with a sharp transition at around 50 K. The resistivity was metallic both along the c-axis and within the ab-plane, with an anisotropy ratio of gamma2 = (rho(c)/rho(ab)) approximately 50 which is almost independent of temperature. Details of the crystal growth, heat treatment procedures, and the results of electrical and magnetic property measurements are presented.
