NMR evidence for enhanced orbital diamagnetism in topologically nontrivial half-Heusler semimetals

Abstract

209Bi nuclear magnetic resonance (NMR) spectroscopy was employed to probe potential spin-orbit effects on orbital diamagnetism in YPtBi and YPdBi crystals. The observed opposite sign and temperature dependent magnitude of 209Bi NMR shifts of both crystals reveal experimental signatures of enhanced orbital diamagnetism induced by spin-orbit interactions. This investigation indicates that NMR isotropic shifts might be beneficial in search of interesting spin-electronic phases among a vast number of topological nontrivial half-Heusler semimetals.
