Diffusive-like effects and possible non trivial local topology on the half-Heusler YPdBi compound

Abstract: The non-ambiguous experimental identification of topological states of matter is one of the main interesting problems regarding this new quantum state of matter. In particular, the half-Heusler family RMT (R = rare-earth, T = Pd, Pt or Au and T = Bi, Sb, Pb or Sn) could be a useful platform to explore these states due to their cubic symmetry and the topological properties tunable via their unit cell volume and/or the nuclear charges of the M and T atoms. In this work, we report electron spin resonance (ESR) an… Show more

“…YPdBi is a well-established topologically trivial half-Heusler system 7 9 based on nuclear magnetic resonance 21 24 , electron spin resonance 25 , 26 and from bulk band structure calculated using density functional theory (DFT) 22 . Although, bulk unstrained YPdBi is topologically trivial, interestingly it was theoretically predicted to undergo a strain-driven transition to a non-trivial state 9 .…”

“…They show clearly different robustness of the diffusive line shape against external parameters (such as grain size and Nd 3+ -concentration). With both having a similar skin depth, and similarly enhanced T 1 's, in principle, a similar robustness of the diffusive asymmetry of the line shape should be expected for the two systems if phonons or electronic trivial excitations were responsible for the diffusive asymmetry; however this is not observed experimentally [49,63].…”

“…However, such interpretation, which is not consistent with Dyson's theory [48,52], has not been observed experimentally and is not supported by at least two other previous experimental observations. The first, and most important, is the coexistence of localized and diffusive ESR line shapes in half-Heusler systems [49,63,68]. Another important example is the local-moment ESR spectra in superconductors, which have highly conducting surfaces and do not show a diffusive-like character [69][70][71][72][73].…”
