摘要
We have synthesized single crystals of K1.00(3)Fe0.85(2)Ag1.15(2)Te2.0(1). The material crystallizes in the ThCr2Si2 structure with I4/mmm symmetry and without K and Fe/Ag deficiencies, unlike in KxFe2-ySe2 and KxFe2-yS2. Transport, magnetic, and heat-capacity measurements indicate that KFe0.85Ag1.15Te2 is a semiconductor with long-range antiferromagnetic transition at T-N = 35 K.
