Abstract

(TTM-TTP)I₃ which has been considered as the typical one-dimensional half-filled band system, has been critically restudied by structural and magnetic measurements. X-ray diffuse scattering study reveals the formation of 2k_F CDW superstructure with the wave vector q₁ =(0, 0, 0.5) below 160 K of the metal-insulator transition temperature. Another structural modulation with q₂ = (0.5, 0, 0.5) is observed below 90-100 K. Modulated structure analysis using the q₂ satellite reflections and the Bragg reflections shows the large displacement in I₃ anion. Anomalies in χ, line width and g-value of ESR measurements which correspond to the structural anomaly, are also reported.
