| Research Abstract |
In this study, we have proposed spin quantum cross devices, which consist of organic molecules sandwiched between two ferromagnetic metals whose edges are crossed. We have theoretically investigated the spin transport characteristics of them using non-equilibrium Green's function. Also, we have made a prototype-spin quantum cross device and verified the theory compared with the experimental results. As a result, we have successfully obtained a general formula for spin transport using Anderson Hamiltonian, and succeeded in realizing a spin quantum cross device experimentally. We have also found that the developed theory predicts the experimental results quantitatively.
