We have studied magnetoresitance in the non-local spin valves based on single crystals of organic conductors. We observed non-local magnetoresistance at the antiparallel configuration of the ferromagnetic electrodes with spacings of a few hundreds nm. The spin diffusion length and spin relaxation time were estimated to be 1100 nm and 3 ns, respectively.We prepared layered spin-valve devices consisting of Co, organic films and Co2MnSi, of which the magnetoresitance was approximately 7 % at room temperature.

我们研究了基于有机导体单晶的非局域自旋阀中的磁阻效应。我们观察到非局部磁电阻在反平行配置的铁磁电极的间距为几百纳米。自旋扩散长度和自旋弛豫时间分别为1100 nm和3 ns.我们制备了由Co、有机薄膜和Co_2MnSi组成的层状自旋阀器件，其室温磁电阻约为7%。
