Abstract

We have investigated the influence of silver on crystallization and oxygenation of the spin ladder compound La₂Cu₂O₅ (four-leg) single crystals. Large La₂Cu₂O₅ single crystals were successfully grown from charges containing Ag₂O by a self-flux method. Electrical resistivity of the silver grown La₂Cu₂O₅ single crystals (∥b-axis) has been found to be about three orders of magnitude lower when compared with the similar crystals grown without silver. Characterizations with optical microscope, XRD, EPMA and HRTEM indicate that the silver does not exist either in free state in the crystal or in the crystal lattice. The results show that the silver facilitates oxygenation in La₂Cu₂O₅ crystals during their growth.
