我们报告了有机导体二[双（亚乙基二硫代）四硫富瓦烯]三碘[（BEDT-TTF）2 I3]在环境压力和高达10 kbar的外加压力下的α和β相的静态磁化率数据χ（T）。环境压力ESR数据为这两个阶段低于300 K。超导体β-（BEDT-TTF）2 I3的自旋磁化率χsβ（T）的温度依赖性对于有机导体来说是非常小的;发现压力导数Δ lnχsβ/Δ P的大小仅为中等（-3.3%/kbar），并且在300 K以下与温度无关。对于αq相，在室温下，ε lnχsα/ε P ε =-2.0%/Kbar。
We report static magnetic susceptibility data, χ(T), for the α and β phases of the organic conductor di[bis(ethylenediothiolo)tetrathiafulvalene] tri-iodide [(BEDT-TTF)2I3] both at ambient pressure and under applied pressures of up to 10 kbar. Ambient pressure ESR data for both phases below 300 K are also presented. The temperature dependence of the spin susceptibility χsβ(T) for the superconductor β-(BEDT-TTF)2I3 is unusually small for organic conductors; the pressure derivative ∂lnχsβ/∂P is found to be only moderate in magnitude (-3.3% per kbar) and independent of temperature below 300 K. For the αq phase, ∂lnχsα/∂P≃-2.0%/Kbar at ambient temperature.
