| Abstract: | Microwave induced d.c. voltage due to inverse a.c. Josephson effect has been observed across bulk samples of multiphase Y2BaSrCu3O8. Results indicate that weakly coupled superconducting grains probably exist up to 26°C. |
| Keywords: | Josephson effect mixed metal oxides high temperature superconductivity |
