Abstract
Single crystals of copper-oxycarbonate (Ba1-xSrx)(2)Cu1.1O2.2+delta(CO
3)(0.9) are obtained by solid state recrystallization and their struct
ures are analyzed by single crystal X-ray diffraction. The size of the
crystals are up to 2x2x2 mm(3), and become superconducting at 32K(ons
et) and 26K(endpoint). Single crystal X-ray diffraction shows that the
crystals have a tetragonal unit cell with lattice parameters a = 5.57
0(2)Angstrom and c = 7.868(2)Angstrom, which are almost equal to those
of ceramic samples.
