Abstract

We carried out a comprehensive study of electronic transport, thermal, and thermodynamic properties in FeCr2Te4 single crystals. It exhibits bad-metallic behavior and anomalous Hall effect (AHE) below a weak-itinerant paramagnetic-to-ferrimagnetic transition Tc∼123 K. The linear scaling between the anomalous Hall resistivity ρxy and the longitudinal resistivity ρxx implies that the AHE in FeCr2Te4 is most likely dominated by an extrinsic skew-scattering mechanism rather than an intrinsic KL or an extrinsic side-jump mechanism, which is supported by our Berry phase calculations.
