Synthesis of a new (Ta1-xSnx)Sr2EuCu2Oz superconductor

초록

We report here results of a study of superconductivity in the (Ta1-x Snx)Sr2EuCu2Oz system. We observe resistivesuperconducting transitions for the samples with x = 0.15-0.3, and the highest superconducting transition has been achieved for thesample with x = 0.2 which reveals onset Tc of 43 K and zero-resistivity of 25 K. Thermoelectric power measurements indicate thatSn doping introduces holes into the system and thereby superconductivity can be achieved in the (Ta1-xSnx)Sr2EuCu2Oz system.
