Fig. 2: Hall effect of Ce3TiSb5 in the paramagnetic state.
From: Rich unconventional Hall effects in a single quasi-kagome Kondo Weyl semimetal candidate Ce3TiSb5
a Isothermal field-dependent Hall resistivity ρyx at different temperatures. Data of the non-magnetic reference La3TiSb5 are also shown for comparison. The inset depicts the schematic of transport measurements. b Hall resistivity divided by field, plotted as a function of T. The inset displays ρyx/H vs. χc with T as an implicit parameter. The linear fitting for \(T > {T}_{K}^{on}\) leads to the normal Hall coefficient RH = +0.6(2) × 10−10 m3/C. The open squares represent the data of La3TiSb5. c Schematic diagrams of Kondo effects: non-screened regime for \(T > {T}_{K}^{on}\), incoherent Kondo regime for \({T}_{coh} < T < {T}_{K}^{on}\), and coherent Kondo regime for T < Tcoh. The hatched balls signify Kondo entanglement of f (red) and conduction (blue) electrons. The upper panel sketches the skew scattering off a Kondo-screened local moment. d ibid, but in a geometrically frustrated lattice. Geometric frustration adds to the inherent frustration caused by Kondo effect, which further weakens the skew scattering in the frustration-promoted incoherent Kondo regime, viz \({\theta }_{{A}^{{\prime} }} < {\theta }_{A}\).
