摘要
在YBCO高T_C超导样品的微波损耗测量中观察到其微波表面电阻R_S(T)曲线存在双转变现象。参照Nb_3Sn低T_C超导材料的类似实验对本实验结果进行了初步分析,认为超导材料的高频电磁特性测盈可以成为一种更灵敏反映材料特性的测量手段。
The double transitions in Rs(T) curve about microwave loss of the YBCO high Tc sample have been observed,Referred to a similar experiment of Nb3 Sn low Tc superconductor, a preliminary analysis of this experimental result has been done. It has been proposed that the measurement of high frequency electromagnetic characteristic of superconductor may become more sensitive than other measuring.
