Abstract —The iron–tellurium-based compounds Fe1.1Te(TiSe2)y doped with titanium diselenide (y = 0, 0.04, 0.08, 0.1, 0.2) have been synthesized for the first time and studied by means of x-ray diffraction, electrical resistivity and magnetization measurements. It has been shown that the addition of a small amount of titanium diselenide to single-phase iron telluride with a tetragonal crystal structure leads to the appearance of superconductivity, a decrease in the Néel temperature and contraction of the crystal lattice at y ≥ 0.04. The maximal temperature of the onset of the superconducting transition Tonsetc ~ 13 K is observed for a sample with the nominal composition Fe1.1Te(TiSe2)0.1. The behavior of the resistivity with temperature below Tconset is observed to depend on the current value, which may indicate superconductivity characteristic of granular superconductors.
