Abstract

Magnetoresistance, magnetization, and reflectance spectra were measured for τ-(EDO-S,S-DMEDT-TTF)₂(AuBr₂)_1+y, (y∼0.75) (EDO-S,S-DMEDT-TTF = ethylenedioxy-S,S-dimethylethylenedithio-tetrathiafulvalene) and τ-(P-S,S-DMEDT-TTF)₂(AuBr₂)_1+y, (y∼0.75) (P-S,S-DMEDT-TTF = pyrazino-S,S-dimethylethylenedithio-tetrathiafulvalene). The saturation of magnetization curve and Drude dispersion imply the weak ferromagnetic and metallic nature of former compound at low temperature. For the comparison with this compound, magnetoresistance of latter salt was measured up to 24 T.
