The com-prehensive Microwave characteristics for large-area superconducting film is obtained firstly inChina. Using this film Microwave Center prepared a cavity, the quality factor Q of which attainedto the-state-of the-art (Q= 13100, at 79 K and 3.04 GHz).展开更多

Structural analysis has shown that conversion from tetragonal to orthorhombic phases, reduction of nonsuperconducting phase and preferential rearrangement of crystal grains are all favorable to the improvement of superconductivity in the YBaCuO film supported by YSZ substrate by proton beam bombardment.展开更多
