(a) Powder XRD patterns and structural refinement results. The data were shown by (+), and the fit is given by the red solid line. The difference curve (the green solid line) is offset. Inset: The single crystal XRD pattern shows the basal plane of crystal is bc-plane. (b) The crystal structure of . Sb atoms in 2D layers (Sb1) are shown by red balls. Sr atoms are denoted by gray balls. Zn and Sb (Sb2) atoms in tetrahedrons (light blue polyhedrons in figure) are denoted by cyan and blue balls, respectively. Blue lines define the unit cell. (c) and (d) Temperature dependence of the in-plane resistivity (c) and Seebck coefficient S(T) (d) in B = 0 T (squares) and B = 9 T (circles) magnetic field, respectively.
(a) The magnetic field (B) dependence of the in-plane magnetoresistance MR at different temperatures. Inset: The field derivative of in-plane MR, dMR/dB, as a function of field (B) at T = 40 K. (b) The fitting of the in-plane magnetoresistance at 100 K. The open squares are the experimental results and the solid line is the fitting result using Eq. (1). In the inset, the linear and the cyclotronic contributions are shown separately.
(a) The magnetic field (B) dependence of the Hall resistivity at different temperatures. (b) Temperature dependence of the low field Hall coefficient for . (c) Arrhenius plot of at high temperature range and the red line is the Arrhenius-law fitting.
