Reply to “Comment on ‘Temperature range of superconducting fluctuations above Tc in YBa2Cu3O7−δ single crystals' ”

In a previous article [M. S. Grbić et al., Phys. Rev. B 83, 144508 (2011)] we reported data on the high-temperature superconductor YBa2Cu3O7−δ collected by a contactless microwave absorption technique, which provided evidence for superconducting correlations over a limited temperature range (10–20 K above Tc). The paraconductivity signal was determined by subtraction of zero-magnetic-field data from 16-T data. In the preceding Comment [D. Sóñora et al., preceding Comment, Phys. Rev. B 102, 176501 (2020)] D. Sóñora et al. argue that a 16-T magnetic field is not enough to quench all superconducting fluctuations in the microwave spectral range above Tc. As is obvious from the experimental data presented here, as well as from the data shown in the original paper, such conclusions disagree with our experimental results. Moreover, our initial experimental findings recently received independent robust confirmation from several different experimental techniques.
