Abstract

The temperature dependence of the structure of the high temperature superconducting ceramic SmBa2Cu3O7 with Tc=92 K was investigated in the temperature range from 1.5 K to 300 K, using neutron diffraction measurements on a powder sample with the MiniSfinks, D2B and DMC diffractometers.
The sensitivity of the experiment for the oxygen and barium substructures was increased by using a mixture of 152Sm, 154Sm and 63Cu isotopes. The role of bounds such as Cu-O, of CuO2 and Ba-O plane distortions, order-disorder phenomena due to oxygen as well as the possibility that Sm exists in a mixed valence state, are discussed.
