TL;DR
This paper investigates the relationship between increased X-ray absorption transparency and vortex expulsion phenomena in cuprate superconductors near their critical temperature Tc, revealing a link between spectroscopic and magnetic properties.
Contribution
It introduces a novel correlation between EXAFS transparency changes and vortex dynamics during the superconducting transition in cuprates.
Findings
Increased EXAFS transmission correlates with vortex expulsion near Tc.
Spectroscopic changes are linked to magnetic flux behavior.
Provides new insights into superconducting transition mechanisms.
Abstract
The increased transmission, observed in the EXAFS region of their X-ray absorption spectra, as cuprate materials go through the superconducting transition temperature Tc is correlated with an increase in Abrikosov Vortex expulsion in zero magnetic field as the temperature T approaches Tc.
