中文摘要A series of Al-doped Mg1-xAlxB2 samples have been fabricated and systematic study on structure and superconducting properties have been carried out for the samples. In addition to a structural transition observed by XRD, TEM micrographs showed the existence of a superstructure of double c-axis lattice constant along the direction perpendicular to the boron honeycomb sheet. In order to investigate the effect of Al doping on flux pinning and critical current properties in MgB2, measurements on the superconducting transition temperature T-c, irreversible field B-irr and critical current density J(c) were performed too, for the samples with the doping levels lower than 0.15 in particular. These experimental observations were discussed in terms of Al doping induced changes in carrier concentration. (C) 2004 Elsevier B.V. All rights reserved.
