| Popis: | A YBa2Cu3 O 6.92 superconductor has been studied in an aberration-corrected scanning transmission electron microscope using a combination of atomic resolution imaging and elemental mapping by electron-energy loss spectroscopy (EELS). YBa2Cu3 O 6.92 has been found to be of a nanostructural state due to local variation of cation composition on a nanometer-sized scale. YBa2Cu3 O 6.92 can thus be considered as a non-single phased material formed of coherently intergrown nanodomains of phases with different cation compositions. |
