Spin-electronics, which utilize not only a charge but also a spin of an electron, have drawn much attention from a viewpoint of developing electronics of the second generation. Based on the first ion radical salt of an organic donor radical exhibiting both conductivity and magnetism, we prepared an ion radical salt of a tetraselenafulvalene-based donor radical the resistivity of which was deceased by -99.5% at 2 K, 12 T, under 15 kbar. Moreover, a molecular device was constructed using a dibrominated tetrathiafulvalene-based donor radical, and the current obtained by this ambipolar device was controlled both by electric and magnetic fields.

从开发第二代电子学的角度来看，不仅利用电荷而且利用电子自旋的自旋电子学已经引起了广泛关注。基于第一种同时具有导电性和磁性的有机供体自由基的离子自由基盐，我们制备了一种基于四硒富瓦烯的供体自由基的离子自由基盐，其电阻率在2K、12T、15℃以下时降低了-99.5%。千巴。此外，使用二溴化四硫富瓦烯基供体自由基构建了分子器件，并且通过该双极器件获得的电流由电场和磁场控制。
