New superconducting T'-(La3+)2-x(RE3+)xCuO4 with isovalent doping (RE = Sm, Eu, Tb, Lu, and Y)

A. Tsukada, Y. Krockenberger, H. Yamamoto +1

We report the synthesis of new superconducting cuprates T'-La2-xRExCuO4 (RE = Sm, Eu, Tb, Lu, and Y) using molecular beam epitaxy. The new superconductors have no effective dopant,…
