Canfield A new type of a topological quantum structure was identified recently in PtSn 4 as a Dirac node arc feature on the surface. More importantly, PtSn 4 shows extremely large magnetoresistance (XMR). PdSn 4 is isostructural with PtSn 4 and has the same electron count. By comparing these similar compounds, the authors address the problem about the origin of the XMR in them and establish that neither the carrier compensation nor the Dirac node arc surface state can be the primary reason for it. On the other hand, Kohler’s rule scaling is fulfilled over the entire range of temperatures and field strengths that are explored here. [Phys. Rev. B 96, 165145] Published Fri Oct 27, 2017
