Abstract :
A novel spin measurement geometry of a nanosized spin device was observed in this study where the current does not pass the ferromagnetic electrode. Also, the spin signals resulted from the interaction between the two ferromagnetic metals (FMs) at the spin device was presented. It was found that the device can be a candidate for spin field effect transistor.
