Overview
- NTNU’s QuSpin-led researchers, working with experimental groups in Italy, studied noncentrosymmetric niobium–rhenium and found behavior that departs from conventional singlet superconductivity.
- The team reports inverse spin-valve and related measurements consistent with intrinsic triplet pairing in NbRe, published in Physical Review Letters and selected as an Editors’ Suggestion.
- Triplet pairing would enable zero-resistance spin currents, a property viewed as promising for spintronics and for improving the stability and energy efficiency of quantum devices.
- NbRe becomes superconducting near 7 K, a comparatively accessible temperature versus some triplet candidates that operate around 1 K.
- The authors caution that definitive identification requires replication by independent groups and further targeted tests, noting conceptual ties to Majorana modes relevant to robust qubits.
