Magnetometry and magnetoresistance (MR) data taken on the van der Waalsferromagnet Fe$_{3-x}$GeTe$_2$ (FGT) reveal three distinct contributions to theMR: a linear negative component, a contribution from closed Fermi-surfaceorbits, and a $H^2$ enhancement linked to a non-coplanar spin arrangement.Contrary to earlier studies on FGT, by accounting for the field dependence ofthe anomalous Hall effect, we find that the ordinary Hall coefficient decreasesmarkedly below 80 K, indicating a significant change in character of theelectrons and holes on the Fermi surface at this temperature. The resultingaltered ground state eventually causes the Hall coefficient to reverse sign at35 K. Our Hall data support the proposal that Kondo-lattice behavior developsin this $d$-electron material below 80 K. Additional evidence comes from thenegative linear component of the MR, which arises from electron-magnonscattering with an atypical temperature dependence attributable to the onset ofKondo screening.

Direct evidence from high-field magnetotransport for a dramatic change of quasiparticle character in van der Waals ferromagnet Fe$_{3-x}$GeTe$_2$
