ANALYSIS OF TWIN DOMAIN STRUCTURE IN YBa2Cu3O7x SUPERCONDUCTOR
【摘要】 <正> It has been confirmed that YBa2Cu3O7-x superconducting phase is an orthorhombic one belonging to the space group Pmmm with lattice constants a=3. 893A, b=3.820A and c=11.688A. There are many twin domains in this superconducting material studied with a TEM in this work. The reason for the formation of this twin domain structure and the characteristics of phase transformation have also been discussed.
