抜粋

We report the X-ray irradiation dose dependence of the magnetic susceptibility in κ-(BEDT-TTF)2Cu[N(CN)2]Cl (κ-Cl) and β'-(BEDT-TTF)2ICl2 (β'-ICl 2). The Néel temperature of 27.5 K in κ-Cl reduces to 24.0 K after irradiation of 240 MGy, while that of 22.0K in β'-ICl 2 does not vary. Taking account of the suppressed amplitude of the dicyanamide vibration modes in the infrared spectra of the irradiated κ-Cl, we suggest that X-ray irradiation modifies the anion structure related to the CN group, which does not hold in β'-ICl2.
