Spin-polarized charge densities
WebNov 11, 2024 · The sign of this spin density is the same as the polarization of F1. Because of a gradient in the spin accumulation, the spins diffuse to the right along the channel until they reach F2. To understand the transport and relaxation of spins in a NSV, it is insightful to view the profile of the spin accumulation or spin ECP along the device.
