Structural Peculiarities and Thermoelectric Study of Iron Indium Thiospinel.

ABSTRACT: The homogeneity range of ternary iron indium thiospinel at 873 K was investigated. A detailed study was focused on two distinct series (y=z): 1) a previously reported charge-balanced (In_0.67+0.33y □_0.33-0.33y )_tetr [In_2-z Fe_z ]_oct S₄ (A1-series; □ stands for vacancy; the abbreviations "tetr" and "oct" indicate atoms occupying tetrahedral 8a and octahedral 16d sites, respectively) and 2) a new charge-unbalanced (In_0.67+y □_0.33-y )_tetr [In_2-z Fe_z ]_oct S₄ (A2-series). Fe atoms were confirmed to exclusively occupy an octahedral position in both series. An unusual reduction of the unit cell parameter with increasing Fe content is explained by
