摘要

We have investigated the superconducting properties of ail oxygen deficient RuSr2GdCu2O8-delta system. We bring out a new feature from the dc magnetization measurement seen both in the field-cooled as well as in the zero-field-cooled state. We propose to link this feature with the Meissner state of the superconducting phase. This stems from the complex situation arising from the simultaneous presence of signals corresponding to two different magnetic orders and of the diamagnetic signal of the superconducting phase. By separating out the contributions from the magnetic ordering, we find the visible presence of diamagnetic signal corresponding to the Meissner phase in this magnetically ordered system. However, signature of superconductivity, thus derived, is absent in a fully oxygenated system. (c) 2005 Elsevier B.V. All rights reserved.
