Abstract

We report on the anomalous Hall studies in magnetic topological insulator Cr0.15(Bi0.1Sb0.9)1.85Te3 microflakes. Using the reversible magnetic field, both the resistance and Hall measurements unveil strong ferromagnetic loops with the Curie temperature of ~13 K. The ferromagnetism is believed to be mediated by the bulk p-type carriers of 1020 cm-3. The temperature-dependent and resistance-dependent scaling behaviors of the anomalous Hall resistance are analyzed, which indicates obvious suppression due to the electron-phonon interaction.
