“…The lattice parameters a, b, and c were obtained to be 15.370(3) Å, 19.420(4) Å, and 4.361(1) Å, respectively, and these values and the positional parameters are in good agreement with the reported ones [5]. Figure 3 shows the total DOS and individual DOS of Zn for La 6 Zn x Sb 15 (x = 0, 2).…”

We discovered superconductivity in the ternary antimonide La 6 ZnSb 15 , and its superconducting properties were discussed through the resistivity, specific heat, and magnetization measurements. The crystal structure of La 6 ZnSb 15 is the orthorhombic La 6 MnSb 15 -type structure consisting of Sb sheets. Its electronic structure indicates that the conduction bands are mainly originated from Sb 5p orbitals in these Sb sheets. The electrical resistivity and magnetization measurements reveal that this compound is a type-II superconductor below 3.7 K. The upper critical field at zero temperature, µ 0 H c2 (0), is determined to be 851(8) mT. In the normal state, the electronic specific heat coefficient, γ, and the Debye temperature, Θ D , are found to be 18.8(8) mJ/mol K 2 and 218(1) K, respectively. From the electronic specific heat in the superconducting state, this compound belongs to a typical weak-coupling BCS superconductor.2

“…This material is an alloy and the electronegativities of the elements involved are not very different from each other. On the other hand, magnetic measurements indicate classical formal charges for rare earth metals and Mn (1). Therefore, we are led to a Zintltype approach in assigning the charges to different Sb substructures.…”
