Abstract
Nuclear magnetic resonance and Knight shift measurements are critical tools in the identification of spin-triplet superconductors. We discuss the effects of spin-orbit coupling on the Knight shift and susceptibilities for a variety of spin triplet multi-orbital gap functions with orbital-singlet character and compare their responses to “traditional” single-band spin-triplet () superconductors. We observe a non-negligible residual spin-susceptibility at low temperature.
