| Research Abstract |
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.
