Query: Extremely large magnetoresistance and Kohler's rule in PdSn4: a complete
  study of thermodynamic, transport and band structure properties   The recently discovered material PtSn$_4$ is known to exhibit extremely large
magnetoresistance (XMR) that also manifests Dirac arc nodes on the surface.
PdSn$_4$ is isostructure to PtSn$_4$ with same electron count. We report on the
physical properties of high quality single crystals of PdSn$_4$ including
specific heat, temperature and magnetic field dependent resistivity and
magnetization, and electronic band structure properties obtained from angle
resolved photoemission spectroscopy (ARPES). We observe that PdSn$_4$ has
physical properties that are qualitatively similar to those of PtSn$_4$, but
find also pronounced differences. Importantly, the Dirac arc node surface state
of PtSn$_4$ is gapped out for PdSn$_4$. By comparing these similar compounds,
we address the origin of the extremely large magnetoresistance in PdSn$_4$ and
PtSn$_4$; based on detailed analysis of the magnetoresistivity, $\rho(H,T)$, we
conclude that neither carrier compensation nor the Dirac arc node surface state
are primary reason for the extremely large magnetoresistance. On the other
hand, we find that surprisingly Kohler's rule scaling of the
mangnetoresistance, which describes a self-similarity of the field induced
orbital electronic motion across different length scales and is derived for a
simple electronic response of metals to applied in a magnetic field is obeyed
over the full range of temperatures and field strengths that we explore.
