摘要
)各阶参数的波动被认为是理解高温超导机制的重要组成部分。为了研究铜基和铁基超导体中的这些波动,我们使用了直流电阻率和非谐振微波吸收的联合测量。通过比较两种方法获得的数据,我们可以提取出La 2−x Sr x CuO 4中的动态电荷密度波、Bi 2 Sr 2 Ca 1−x Y x Cu 2o 8中的超导波动和FeTe 1−x Se x中的向列波动的贡献。
Fluctuations of various order parameters in cuprate and Fe-based superconductors as revealed by microwave absorption measurements
) Fluctuations of various order parameters are considered as the significant components of understanding the mechanism of high-T c superconductivity. To study these fluctuations in the cuprate and Fe-based superconductors we use the joint measurements of direct current resistivity and non-resonant microwave absorption. Comparing data obtained with both methods allowed us to extract the contribution of dynamic charge density waves in La 2 − x Sr x CuO 4 , superconducting fluctuations in Bi 2 Sr 2 Ca 1 − x Y x Cu 2 O 8 and nematic fluctuations in FeTe 1 − x Se x .
