Crystal Growth and Room-Temperature Intrinsic Anomalous Hall Effect in Cr_0.03Sn_0.05Pb_0.02Te_0.1 Ferromagnetic Crystals

Most of topological crystalline insulators show no presence of intrinsic ferromagnetism at and above room temperature. Here, we report the Cr0.03Pb0.02Sn0.05Te0.1 ferromagnetic crystal prepared through the modified Bridgman route that possesses intrinsic above room-temperature ferromagnetism with Tc ∼335 K and magnetic moments ∼8.85 emu/g. The presence of the anomalous Hall effect in Cr0.03Pb0.02Sn0.05Te0.1 crystals verifies above room-temperature intrinsic ferromagnetism, indicating a great potential of the Cr0.03Pb0.02Sn0.05Te0.1 crystal for many spintronic and topological devices.
