【摘要】 测量不同粒度及低真空条件下高Tc超导样品Bi-Pb-Sb-Sr-Ca-Cu-O的非共振微波吸收信号,实验表明,这个对温度和磁场十分敏感的信号还与样品颗粒的大小及氧气氛有关;并经计算证明,信号强度与近表面趋肤深度壳层Meissner态的体积成正比。更多还原

【Abstract】 No-resonant microwave absorption signals in BiPI SbSrCaCuO samples with different si zes and in coarse vacuum were measured, the experiment showed that the signals related to the grain size of the sample and oxygen atmosphere. The signal intensity was proportional to the Meissner state volume which was a shell layer of the skin effeet in the penetration layer.更多还原
