abstract
We report 27Al Knight shift ( 27K) measurement on a single-crystal UNi2Al3 that reveals a coexistence of superconductivity and a spin-density-wave (SDW) type of magnetic ordering ( TSDW = 4.5 K). The spin part of 27K, 27Ks, does not change down to 50 mK across the superconducting (SC) transition temperature Tc∼0.9 K. In contrast with the isostructural compound UPd2Al3 ( Tc∼2 K), which was identified to be a spin-singlet d-wave superconductor, the behavior of 27K strongly supports that UNi2Al3, like UPt3 and Sr2RuO4, belongs to a class of spin-triplet SC pairing state superconductors.
