Claims

C1strongest claim

Eu-doped infinite-layer nickelate Sm_{0.95-x}Ca_{0.05}Eu_xNiO_2 exhibits a magnetic-field-induced re-entrant superconducting phase in the Eu-rich over-doped regime, confirmed by zero-resistance transport and high-field diamagnetic screening.

C2weakest assumption

The interpretation that zero-resistance transport combined with diamagnetic screening unambiguously establishes a true superconducting phase rather than an anomalous metallic or other non-superconducting state, and that the observed deviations from the Eu-exchange-field compensation model reflect new physics rather than experimental artifacts or sample inhomogeneity.

C3one line summary

Eu-doped infinite-layer nickelates exhibit field-induced re-entrant superconductivity in the over-doped regime, with nonlinear Hall transport and hysteretic magnetoresistance indicating unconventional behavior.
