在[（DT-TTF）（2）][Au（mnt）（2）]上进行的零场和纵场mu（+）SR随温度变化的测量证实了该化合物是一种具有两条腿自旋梯构型的分子材料。结果证实了理论预期的情况下，在偶数腿自旋梯与量子自旋液体状态实现的磁秩序，尽管有点强的梯子梯子的相互作用。缓慢波动的局部领域是明显的低于20 K，可能源于链断裂。[S0163-1829（99）13729-9]。
Zero-field and longitudinal field mu(+)SR measurements as a function of temperature on [(DT-TTF)(2)][Au(mnt)(2)] have confirmed that this compound is a molecular material with a two-leg spin-ladder configuration. The results corroborate the theoretical expectations for the absence of magnetic order in even-leg spin ladders with the quantum spin-liquid state realized, despite the somewhat strong ladder-ladder interactions present. Slowly fluctuating local fields are evident below 20 K and could originate from chain breaks. [S0163-1829(99)13729-9].
