抄録

We grew single-crystalline Sr_1-xLa_xCuO₂ thin films of electron-doped infinite-layer compounds by molecular beam epitaxy. Crucial to our success was the use of KTaO₃ substrates. The best film showed T_c^onset=41.5 K and T_c^zero=39.0 K. The resistivity of the optimum-doped films exhibited metallic temperature dependence with a low resistivity of 320 μΩcm at room temperature and 120 μΩcm just above T_c. Such excellent electrical properties have not previously been reported for this system with either thin films or bulk polycrystalline specimens.
