Abstract

The compounds Gd2Ba2Cu2Ti2-xMxO11-δ (M = Al, Co) were prepared and characterized by X-ray diffraction. The structure was refined by Rietveld calculations. Additional investigations such as magnetic measurements and impedance spectroscopy were performed in order to determine the physical properties of Gd2Ba2 Cu2 Ti2 M011-δ. SQUID measurements revealed the presence of a superconducting phase in the compound with the formal composition Gd2Ba2Cu2Ti1.6Al0.4011-δ. A transition temperature (Tc) of 25 K was observed.
