Fig. 4: The out-of-plane thermal Hall κxz(H) and Lxz(H) of NdAlSi.
From: Abnormally enhanced Hall Lorenz number in the magnetic Weyl semimetal NdAlSi
Data were measured with H∥[010](b) (see Supplementary Note 5 for details of the derivation of κxz.) Top panels: Experimental κxz(H) (solid diamonds) compared with the electronic contribution \({\kappa }_{xz}^{{{{\rm{WF}}}}}={L}_{0}{\sigma }_{xz}T\) (solid lines) estimated based on a valid WF law. Bottom panels: Lxz(H) determined from κxz(H). The horizontal lines denote the Sommerfeld value L0. a T = 10 K, b T = 20 K, c T = 50 K, d T = 100 K, e T = 150 K, f T = 200 K.
