抄録

The locations of Sr atoms in a crystal of the Bi–Pb–Sr–Ca–Cu oxide superconductor consisting of the high-T_c phase were studied by high-resolution analytical electron microscopy (HRAEM) with a spatial resolution of 17 Å using a probe 5 to 10 Å in diameter. The HRAEM showed that not only Pb atoms, but also Sr atoms were located in the Bi–O layers, indicating that these atoms might be hole donors in the Bi–Pb–Sr–Ca–Cu–O superconductor.
