Single crystal growth and intrinsic anomalous Hall effect of Cr_2.70Se_0.60Te_3.40 ferromagnetic crystals

Recent discoveries of intrinsic ferromagnetism in low-dimensional ultrathin crystals offer a unique platform for investigating the basics of magnetism and fabricating devices that make use of spins. Here, we report the growth of Cr2.70Se0.60Te3.40 crystals by the chemical-vapour-transport technique. These crystals exhibit ferromagnetism with Curie temperature similar to 245 K and magnetic moment similar to 7.15 emu g(-1). The nanosheets of Cr2.70Se0.60Te3.40 single crystals possess intrinsic ferromagnetism verified by the anomalous Hall effect, showing the great potential of Cr2.70Se0.60Te3.40 crystals for the fabrication of spintronic, data storage and topological devices.
