Comparison of the two terms contributing to vN in LSCO. As discussed above, vN is the sum of two competing terms, as shown in the equation above the figure. The term S*tan(\theta)/B is determined by measuring the thermopower S and the Hall angle \theta separately. We plot this term for the 3 samples (0.07, 0.10, 0.12) on the right scale. Comparing them with the observed total v, we find that S*tan(\theta)/B is much larger than vN (about 30 times larger in the 0.07 sample). We conclude that the anomalous part v-vN cannot arise from the normal state charge carriers even at 150 K. [Xu et al. Nature 2000].
