概要

論文の詳細を見る
The preparation of a single crystalline powder of superconducting YBa_2Cu_3O<7-x> was investigated for the gas phase solidification process by decomposing an evaporated solution of yttrium, barium and copper acetates. A transmission electron microscope observation of particles less than 0.3 μm in diameter showed that the as-produced particles were twinned at transformation to orthorhombic YBa_2Cu_3O<7-x>. The as-produced powder was a single phase YBa_2Cu_3O<7-x> and did not exhibit an isomer from the X-ray diffraction pattern.
