Figure 8: Structure, resistivity, magnetization, and specific heat characterizations of SrBi3 single crystal.
From: Spin-orbit coupling enhanced superconductivity in Bi-rich compounds ABi3 (A = Sr and Ba)
(a) Powder XRD pattern of SrBi3 crushed from many single crystals. The red bars are SrBi3 in PDF card. The inset shows the studied SrBi3 single crystal. (b) Temperature dependence of resistivity of the polished SrBi3 single crystal. The solid line is the Fermi liquid fitting at the low temperature. The inset shows the Bloch-Grneisen-Mott (BGM) model fitting of the resistivity. (c) ZFC and FC magnetic susceptibility of SrBi3 single crystal measured at H = 10 Oe. The superconducting temperature Tc is 5.75 K. The inset shows the magnetic field dependence of magnetization at T = 5 K. (d) Heat capacity of SrBi3 single crystal measured under H = 0 T and H = 5 T. The upper inset shows the 
versus T, the solid line is fitting according to 
. The lower inset shows the 
versus T 2.
