(color online) Characterization of . (a) A schematic drawing of crystal structure. Single crystal SrMnSb₂ is composed of two formula layers (SrSb and MnSb), stacking along the axis. (b) X-ray diffraction pattern of on the (00l) plane. The XRD pattern peaks of our sample match well with the stoichiometric coordinate. (c) The temperature dependence of in-plane resistivity. A constant current was applied within the bc plane. The inset shows the geometry of Hall bar. (d) The carrier density and mobility at different temperatures. The mobility of the sample exceeds at 2.5 K.
