The role of the nominal iron content in the structural, compositional and physical properties of BaFe${}_{2+\delta }$S${}_3$

M. L. Amigó, Q. Stahl, A. Maljuk +6

BaFe${}_2$S${}_3$ is a quasi-one-dimensional antiferromagnetic insulator that becomes superconducting under hydrostatic pressure. The magnetic ordering temperature, $T_N$, as well as t…
