Summary We report on low-temperature (4.2 K)57Fe Mössbauer studies of the ternary alloy system Fe(Sb1−x Te x )2 for 0.5≤x≤1.0. The Mössbauer spectra are electric-quadrupole doublets for all the specimens, indicating a non-magnetic character. The quadrupole splitting decreases with the increase in tellurium concentration. FeTe2 has also been studied in external magnetic fields up to 6T. These experiments show that the electric-field gradient in this alloy is negative and has an asymmetry parameter of η ≈0.7.
