SdH oscillations in YPdBi crystal.
(a) The variations of ΔR⊥ vs. 1/H, after subtracting a fitted smooth background at various temperatures. (b) Temperature dependence of the SdH oscillation amplitude ΔR⊥ (T)/R⊥ at 9 T. The solid line is a fit to the Lifshitz-Kosevich formula, from which we extract Landau level (LL) energy gap ΔEN. The inset shows ΔEN as a function of H (magnetic field positions of minima in R⊥ corresponding to different LLs) and the effective mass: ~0.09 me is extracted from the slope of the linear fitting. (c) Dingle plots of ln versus 1/H at different temperatures. The Dingle temperature TD = 6 K is calculated from the slope of the linear fit, corresponding to a carrier lifetime τ~4 × 10−13 s and an effective mobility of 7800 cm2 V−1s−1.
