Abstract
We report successful growth of magnetic topological insulator (MTI) MnBi(2)Te(4)singlecrystalby solid state reaction route via self flux method. The phase formation of MnBi(2)Te(4)singlecrystalis strongly dependent on the heat treatment. MnBi(2)Te(4)is grown in various phases i. e., MnBi4Te7, MnBi6Te10 and MnTe as seen in powder X-ray diffraction (PXRD) of crushed resultant crystal. The Rietveld analysis shows some impurity lines along with the main phase MnBi2Te4. Low temperature (10K) magneto-resistance (MR) in applied magnetic field of up to 6 Tesla exhibited - ve MR below 0.5 Tesla and +ve for higher fields. The studied MnBi2Te4, MTI crystal could be a possible candidate for Quantum Anomalous Hall (QAH) effect. Here we are reporting a newly discovered magnetic topological insulator MnBi(2)Te(4)having non-trivial symmetry as well as strong Spin-Orbit Coupling forQAH effect.
