Residual spin susceptibility in the spin-triplet, orbital-singlet model

Abstract

Nuclear magnetic resonance (NMR) 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 ($p_x+i{p}_y$) superconductors. We observe a non-negligible residual spin-susceptibility at low temperature.
