Superconductivity and Magnetism in Bi-Ni System: From Bulk to Heterostructures
Gabriel Sant'Ana, Yutao Xing, Milton A. Tumelero
Unconventional superconductivity with ingredients of magnetism such as time reversal breaking, triplet pairing and proximity effects has been a long time pursued topic in physics a…
Emergent Zeeman-Resilient Superconductivity Beyond the Spin-Paramagnetic Limit in Ultrathin NiBi3
Gabriel Sant'Ana, Leonardo Pessoa da Silva, Pedro Schio +4
The spin-paramagnetic limit sets a fundamental magnetic-field bound for conventional superconductors. Here we show that ultrathin NiBi films develop a highly field-resilient su…
Linear Magnetoresistance and Anomalous Hall Effect in the Superconductor NiBi
Gabriel Sant'ana, Jully Paola Peña Pacheco, David Mockli +4
The NiBi compound exhibits a compelling interplay between superconductivity and magnetism, further enriched by topological characteristics that make it an exceptional platfor…
Ni/Bi bilayers: The effect of thickness on the superconducting properties
Gabriel Sant'ana, David Möckli, Alexandre da Cas Viegas +2
Nickel/Bismuth (Ni/Bi) bilayers have recently attracted attention due to the occurrence of time-reversal symmetry breaking in the superconducting state. Here, we report on the stru…
