Anomalous Hall effect in trigonal Cr${}_5$Te${}_8$ single crystal

We report anomalous Hall effect (AHE) and transport properties of trigonal Cr${}_5$Te${}_8$ (tr-Cr${}_5$Te${}_8$) single crystals. The electrical resistivity as well as the Seebeck coefficient shows a clear kink at the paramagnetic-ferromagnetic transition of tr-Cr${}_5$Te${}_8$, which is also confirmed by the heat capacity measurement. The scaling behavior between anomalous Hall resistivity ${\rho }_{xy}^A$ and longitudinal resistivity ${\rho }_{xx}$ is linear below $T_c$. Further analysis suggests that the AHE in tr-Cr${}_5$Te${}_8$ is dominated by the skew-scattering mechanism rather than the intrinsic or extrinsic side-jump mechanism.
