Unusual persistence of superconductivity against high magnetic fields in the strongly-correlated iron-chalcogenide film FeTe:Ox

We report an unusual persistence of superconductivity against high magnetic fields in the iron-chalcogenide
 film FeTe:Ox below ≈ 2.5 K. Instead of saturating like a mean-field behavior with a single order parameter, the
 measured low-temperature upper critical field increases prog...

description We report an unusual persistence of superconductivity against high magnetic fields in the iron-chalcogenide
 film FeTe:Ox below ≈ 2.5 K. Instead of saturating like a mean-field behavior with a single order parameter, the
 measured low-temperature upper critical field increases progressively, suggesting a large supply of superconducting
 states accessible via magnetic field or low-energy thermal fluctuations. We demonstrate that superconducting
 states of finite momenta can be realized within the conventional theory, despite its questionable
 applicability. Our findings reveal a fundamental characteristic of superconductivity and electronic structure in
 the strongly-correlated iron-based superconductors.
