Absence of the Zeeman effect on the Maki-Thompson fluctuation in magnetoresistance of YBa2Cu3O7 single crystals

Abstract
We experimentally demonstrated the absence of the Zeeman effect on the Maki-Thompson fluctuation in the Aronov-Hikami-Larkin theory. Moreover, we fine that clean-limit analysis without the MTZ component closely fits the experimental data. Our analysis provides a quantitatively consistent picture of Y-Ba-Cu-O icluding transport and optical studies.
