Abstract :

The structure, Raman spectrum, and superconducting properties of a series of polycrystalline bulk samples of [Mg.sub.(1-2x)][(AgAl).sub.x][B.sub.2] (0.0% less than equal to x less than equal to 1.0%) synthesized by a solid-state reaction method are investigated using x-ray diffraction, Raman spectroscopy, and low-temperature resistivity measurements. Results reveal that the Ag, Al double doping causes the expansion of crystal lattice along the a- and c-axis orientations due to the substitution inducing ionic size variation.
