“…We have considered electronic excitation mediated mechanism to examine pairing between two electrons in a band, involving singlets with the possible mixture of s-wave like and d-wave like character of the pair wave function. This is very much plausible in view of the experimental results on real materials [1, [3][4][5].…”

“…Alternative ideas and explanations have since then appeared in the literature. 12,13,14,15,16,17,18 Most of them are based on a small overlap of electronic wave-functions in the direction of the magnetic field, but suggestions based on a Luttinger liquid approach have also been made 19,20 . The theory developed by Osada, Kagoshima and Miura 12 captures many details of the experimental data 21 .…”

The dependence of the magnetoresistance of quasi-one-dimensional metals on the direction of the magnetic field show dips when the field is tilted at the so-called magic angles determined by the structural dimensions of the materials. There is currently no accepted explanation for these magic-angle effects. We present a possible explanation. Our model is based on the assumption that, the intralayer transport in the second most conducting direction has a small contribution from incoherent electrons. This incoherence is modeled by a small uncertainty in momentum perpendicular to the most conducting (chain) direction. Our model predicts the magic angles seen in interlayer transport measurements for different orientations of the field. We compare our results to predictions by other models and to experiment.

“…Such a marked up-turn behavior has been commonly attributed to a magnetic-field-driven metalinsulator transition, 17,[19][20][21][22]34,35 although few publications questioned such an interpreattion. 10,36,37 In WTe 2 , an electronic structure change has also been proposed to be a possible origin. [38][39][40][41][42] Here we tackle the issue of the MRs turn-on temperature behavior.…”

Origin of the turn-on temperature behavior inWTe2

A hallmark of materials with extremely large magnetoresistance (XMR) is the transformative turnon temperature behavior: when the applied magnetic field H is above certain value, the resistivity versus temperature ρ(T ) curve shows a minimum at a field dependent temperature T * , which has been interpreted as a magnetic-field-driven metal-insulator transition or attributed to an electronic structure change. Here, we demonstrate that ρ(T ) curves with turn-on behavior in the newly discovered XMR material WTe2 can be scaled as MR ∼ (H/ρ0) m with m ≈ 2 and ρ0 being the resistivity at zero-field. We obtained experimentally and also derived from the observed scaling the magnetic field dependence of the turn-on temperature T * ∼ (H − Hc) ν with ν ≈ 1/2, which was earlier used as evidence for a predicted metal-insulator transition. The scaling also leads to a simple quantitative expression for the resistivity ρ * ≈ 2ρ0 at the onset of the XMR behavior, which fits the data remarkably well. These results exclude the possible existence of a magnetic-field-driven metal-insulator transition or significant contribution of an electronic structure change to the lowtemperature XMR in WTe2. This work resolves the origin of the turn-on behavior observed in several XMR materials and also provides a general route for a quantitative understanding of the temperature dependence of MR in both XMR and non-XMR materials.
