Current Spin Polarization

Current spin polarization in ferromagnetic/organic system is theoretically studied based on the spin diffusion theory and Ohm's law, and the effects of the spin-related interfacial resistances on the spin-polarized injection are discussed. It is shown that the current spin polarization can be higher than the spin polarization of the ferromagnetic contact and may reach 100% at the interface by modulating the spin-related interfacial resistances. The proposed amplification scheme provides an efficient way to generate a highly spin-polarized current in organic materials because of the easy fabrication of ordered spin-related tunnel barriers at contact structures.

Match Level

The spin-dependent electronical conductivity of polarons is studied in the spin polarized organic semiconductor .It is found that the spin dependence of the electronical conductivity is induced by the spin polarization of the organic semiconductor, for the spin polarization makes the up-spin and the down-spin polarons have different density, which generates the spin-dependent electronocal conductivity. The spin-dependent electrical conductivity can be directly affected by the match level of conductivities s0/sf at the interface of the FM/OSE. Moreover, the current spin polarization in the organic semiconductor can be strengthened by the electric-field in the low-electric-field region .
