Research Abstract |
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.
