Abstract

We have studied local structure of IrTe2 by Ir L3-edge extended x-ray absorption fine structure (EXAFS) measurements as a function of temperature to investigate origin of the observed structural phase transition at Ts∼270 K. The EXAFS results show an appearance of longer Ir-Te bond length (ΔR∼0.05 Å) at T
