Evolution of the crystal and electronic structures of magnetic RuSr(2-x)La(x)GdCu2O8 superconductors upon La substitution.

We have investigated systematically the effects of La substitution on the chemical bonding nature and physical properties of magnetic RuSr(2-x)La(x)GdCu2O8 superconductors. X-ray diffraction and energy dispersive spectroscopic microprobe analyses reveal that a fraction of Sr ions can be successfully replaced by La ions with the contraction of unit cell… CONTINUE READING
